That's why the Earth lost any primordial hydrogen and helium envelope it might have had. More posts from the askastronomy community. They are no bigger than a city. Normal stars (meaning ones that fuse hydrogen into helium in their cores) are much bigger than planets. As I recall, above a certain size, planets get smaller with increasing mass because the pressure at their core gets great enough to compress the hydrogen enough to make that possible. 6 Answers. A gas giant with at least twice Jupiter’s mass, it orbits Pollux at a distance of 1.65 astronomical units — a little farther from its star than Mars is from the Sun. 6 months ago. Hide Caption But there could be some instances in which exoplanets may appear larger than the host star, such as when the host star is a neutron or white dwarf star instead of a more traditional variant like our Sun. In fact, most objects between 0.3 Jupiter masses and 80 Jupiter masses, whether a planet, brown dwarf, or star, are roughly the same size. Remember the difference between a Brown Wolff and a main sequence star is whether the nuclear fusion takes place in the Stars Core, which we believe … The planets in our solar system are much closer to the Earth. Press question mark to learn the rest of the keyboard shortcuts. Our solar system has but one planet orbiting in what is commonly known as the habitable zone — at a distance from the host star where water could be liquid at times rather than always ice or gas. http://web.archive.org/web/20201213061638/https://www.popularmechanics.com/space/deep-space/news/a27260/smallest-star-ever-discovered-by-astronomers/. If the planet is made of metal (a technical term among astronomers that means anything by hydrogen or helium), it will be harder to fuse, so it can be bigger without being a star. Of course, as a main sequence star (not a brown dwarf), it has to be a lot more massive than Jupiter. UY Scuti (BD-12°5055) is a red supergiant star in the constellation Scutum.It is considered one of the largest known stars by radius and is also a pulsating variable star, with a maximum brightness of magnitude 8.29 and a minimum of magnitude 10.56. Rules: https://www.reddit.com/r/askastronomy/about/rules A planet orbits a star, and only a star. Show me what you got... 3 comments. John. This star is probably an ultracool M-dwarf. If it was in an area of the universe where there was a significant amount of stray gas then it would attract it inwards, and I can't see why it couldn't have a few (cold and barren) planets. The KELT-9b planet was found using one of the two telescopes called KELT, or Kilodegree Extremely Little Telescope. While these hypothetical exoplanets could appear larger at first glance, that’s because they’d only be larger volumetrically. As the star is a white dwarf it didn't start out this way, the star would have been larger than the planet, but when it ended it's main sequence lifetime the star would have swelled into a giant, swallowing the planet. Even though it is considered a "dwarf" it is bigger than 90% of the stars in the Milky Way. Favourite answer. A moon is always smaller than the planet it belongs to, but some large moons are bigger than small planets. It might seem to disappear, but some light in a corona shape, would still be technically heading towards us. As they get more massive they get denser but not bigger. The planet's 50 times closer to the star than the Earth is the Sun, but it is as cool as Jupiter. Yes, a giant planet similar to Jupiter could be orbiting a neutron star (which is not much bigger than the Earth. Others have answered, and I agree that it is theoretically possible for a red dwarf system. Answer Save. It must be big enough to have enough gravity to force it into a spherical shape. They think that if it just formed from a cloud of gas, then it’s nothing more than a not-quite-star. what about planets arround a pulsar? If a star had a planet larger than it and if that planet happened to transit its sun as seen from Earth, then yes that "transit" would actually be an eclipse and the star would completely disappear for a short time. The reason for differing brightness is because starts reflect the light of the sun, which is close to the planets, while the stars emit their own light. Make this planet too big and you risk losing ozone. Astronomers have found the tiniest full-fledged star known, an object just 16 percent bigger than Jupiter. Jupiter carries almost 318 times the mass of Earth, making the most massive planets possible the equivalent of nearly 3,200 Earths. Posted by Danny Shook at July 18, 2020. Earth is about the size of an average sunspot! WD 1856 b was discovered last year. That's fundamentally caused by an increased fraction of interior degenerate matter in the form of liquid metallic hydrogen, which has the wacky property that the more of it you add, the smaller it gets. It could also just mean that it's not causing fusion. It is a Jupiter sized planet orbiting a roughly Earth-sized white dwarf! In terms of mass, neutron or white dwarf stars could be packing ten solar masses’ worth of matter into a blob about the size of a metropolitan city. It is so large that about 1,300,000 planet Earths can fit inside of it. Are you confusing the idea of a star's size (its volume) with that of its mass, or are you just assuming that a more massive object has to have a larger volume? I … And when the planet passes in front of the star, will that star like disappear from view completely when looked through telescope? Jupiter is about as big as a planet can be without becoming a star. This means that there can be drastic changes in luminosity due to surface activity, such as star spots (the extrasolar equivalent of sunspots). No, not possible. Of course a star is always much more massive than a planet, but in rare cases a star can be smaller than a giant planet. ... For the first time, scientists have found water on the moon's sunlit surface. What I don't know is whether a Jupiter mass planet could form close enough to a star as massive as EBLM J0555-57Ab. I didn't see anyone answer the second part of your question. Our planet would also be made of the wrong stuff- White dwarfs (and thus, theoretically, black dwarfs) are made of Carbon and Oxygen- most stars aren't hot enough to fuse all the way to iron. you need a telescope to see some of the planets.a star twinkles.a planet glows. A planet can only get so massive before it starts fusing its own atoms together, at which point it can't get any larger, just more dense. Well before that, though, cold giant planets reach their maximum radius around 3 Jupiter-masses, and start shrinking in radius as mass increases from there. The leading scientific social networking website and producer of educational virtual events and webinars. Gas planets, like Saturn and Jupiter are pretty much made of the same stuff as our Sun. See /r/telescopes! It is so large that about 1,300,000 planet Earths can fit inside of it. The reason for differing brightness is because starts reflect the light of the sun, which is close to the planets, while the stars emit their own light. It is actually possible (although unlikely) for a planet to be hotter than other stars as long as the star it orbits around is even hotter. The Sun has about 1000 times the mass of Jupiter. So far, they are just theoretical objects. If you want to watch a video about that topic here's one: Can a planet be bigger than its star. The smallest star, EBLM J0555-57Ab, is 85.2 Jupiter masses and 0.84 Jupiter radius, a little bigger radius than Saturn. This way bigger than the most massive asteroid ever recorded, Ceres, which is … It can happen. By using our Services or clicking I agree, you agree to our use of cookies. Can a planet be bigger than it's parent star? Now, we don't know what all can happen in the greater universe. If you can't tell whether an object in the sky is a star or planet, you'll want to learn how to distinguish between the physical features of these two celestial bodies, and when it's best to view them. Direct your astronomy related questions here! A planet can only get so massive before it starts fusing its own atoms together, at which point it can't get any larger, just more dense. The most recent definition of a planet was adopted by the International Astronomical Union in 2006. A star is what planets orbit around. Lighter gases escape easier from a given planet than do heavy gases. As a general rule of thumb, the vast majority of observable host stars are considerably larger than the exoplanets that orbit them. Researchers say that a space rock that landed in Costa Rica on April 23rd, 2019, came from an asteroid that exists as a (White dwarfs also shrink as they get more massive for the same reason.). Posted by Danny Shook at July 18, 2020. Just one handy quote: The Sun weighs about 333,000 times as much as Earth. share. a star is way bigger than a planet. ... Navigating beyond Earth's orbit is tricky. Yes, in fact the first confirmed extrasolar planet is bigger than its star: The planet PSR B1257+12b has a radius of at least 7500km, and its star PSR B1257+12 (which … While the star is currently twice the Sun’s mass, it’s expected to puff off enough of its outer layers to enable its core to collapse into a … However, not all of the moons are smaller than all of the planets. That's a little unsettling. The night sky is full of light, most of which is generated by celestial bodies like stars and planets. This illustration depicts Kepler-62e, a planet in the habitable zone of a star smaller and cooler than the sun. Favourite answer. Also, is there a size limit we can expect from planets? Yes, the largest exoplanets are larger than the smallest stars. Related: Everything you need to know about exoplanets. It is a Jupiter sized planet orbiting a roughly Earth-sized white dwarf! Stars do the reverse, because as they get larger, their energy output increases, causing a star to puff up, but this particular star is just barely massive enough to fuse protium (the most common isotope of hydrogen), so its energy output is very low. So it's a little odd to think of a planet being bigger than a star, but we're not talking about a normal star here. What is the biggest planet we know of? 0 3. Planets are larger than moons. otherwise, A star(not solar remnants) will always be bigger than its planets. Neutron stars however would be fairly easy to block out, even a large asteroid(>10 km) could completely cover it. Neutron stars aren't really stars. The planet found using TESS, WD 1856b, is about 10 times bigger than Earth (so slightly smaller than Jupiter) and orbits the star at a distance of just 3 million kilometers, which is close — Mercury's orbit around the Sun is 15 times wider — and circles the white dwarf once every 34 hours. Volume-wise, they're much smaller than non-white dwarfs. Relevance. A neutron star has a large amount of mass in a very small space. Lv 7. Moons are always smaller than the planet that they orbit (move around). On August 7, A SpaceX recovery vessel called GO Navigator brought the Crew Dragon capsule back to its home port. This main sequence star is the size of Saturn. No, it is impossible for a planet to be bigger than a star, it it were, it would have became a star itself. ... Scientists hope to use 3D modeling in the future to understand how a rocky planet around a dim star could fare as well. Lv 7. These two stars constitute a BY Draconis variable. As the star is a white dwarf it didn't start out this way, the star would have been larger than the planet, but when it ended it's main sequence lifetime the star would have swelled into a giant, swallowing the planet. Generally, stars are also bigger than planets. (Please read our subreddit rules first!) I want to build a planet (or satellite) that: is smaller than Earth, has a thicker atmosphere than Earth but breathable, has neither intense volcanism, nor any extreme condition of that sort that would increase atmosphere density, revolves around a binary star similar to BY Draconis; A higher gravity makes for a higher atmosphere density. Haven't even done orbital mechanics since undergrad, and I've gotten rusty. What is bigger than the Sun and all the planets yet lighter than air? So, with this in mind, is it even possible for a planet to be larger than its host star? We know that these kinds of circumstances exist, but we have yet to observe such an instance where the two reside in the same system together in nature, and that’s one of the biggest challenges behind answering this age-long question. The Goldilocks Zone is often referenced (an area around a planet’s host star which could be ‘just right’ for liquid water to exist) when it comes to habitability. Or maybe it was created around a star and it somehow got flung off into space. Researchers have shown that it would need a reflective disc 19 times bigger than the Earth's diameter to achieve the orbital change over a timescale of one billion years. I think OP was asking if a planet can possibly be large enough to be larger than its main sequence star as a matter of happenstance, rather than if its possible for stellar remnants to be smaller than the orbiting planets. Would it be torn apart by the tidal forces? The new measurement of HR 5171 A shows they can be much bigger. 75% Upvoted. Any planet orbiting component A or B would not be conducive to life. For a white dwarf, they are much denser and can be a couple of percent of the radius of the Sun. If the star that created those elements is still there when the planet is being formed, it is fully possible that the star has a smaller radius than the planet orbiting it (like a neutron star), but the star will also be much denser than the planet, ensuring that the centre of the orbit is nearer to the star than the planet. Danny Shook “If you want to forget something or someone, never hate it, or never hate him/her. It would likely not disappear, due to the gravitational lensing of the light. Can a planet be bigger than it's parent star? yet, both stars and planets have different sizes, such as a white dwarf star is smaller than Jupiter. Edit: I forgot to say that the white dwarf remains much more massive than the planet. Regarding shape, stars appear as a dot while planets appear spherical. With the recent explosion of extrasolar planet discoveries, some relatively nearby, astronomers and space enthusiasts wonder how habitable some of these planets would be for humans. Exoplanet Habitable Zone Around Sunlike Stars Bigger Than Thought. New comments cannot be posted and votes cannot be cast. The Sciences This Giant Planet is 4 Times Bigger Than its Dead Star Astronomers discovered a Neptune-sized planet orbiting an Earth-sized star. (23 January 2018 - Johns Hopkins University) A planet can be no bigger than about 10 times the mass of Jupiter, an astrophysicist has concluded. Simply because of the necessary size of the Star, its luminosity would make it difficult to observe. It orbits its star in only about 10 Earth-days. Jupiter is about as large a planet as you can get, and it's still only 1/10th the diameter of the Sun. It is possible if the star is a white dwarf or a neutron star. That being said, the planet would still need to be fairly large like Neptune or larger. More info at it's wikipedia page: https://en.wikipedia.org/wiki/WD_1856%2B534. Short answer is NO. There are some exoplanets that are larger than Jupiter, but that's because they orbit much closer to their parent star than does Jupiter. The planet is ten times larger. But we don't even need to consider them, because red dwarfs can be smaller than Jupiter. Relevance. Stellar remnants like white dwarves, neutron stars, etc are a different story—they are post-star objects that started out much larger than their planets, even if they became smaller after they ran out of fuel, went supernova, etc. The planet is ten times larger. The planet is rare, although astronomers don't know why planets orbiting evolved stars are so absent. And that is why stars are bigger than the planets. A Jupiter mass planet could easily orbit a star of that size, in the sense that Jupiter orbits our sun. The smallest planet in the solar system is Mercury which has a diameter of about 3,032 miles. It says a planet must do three things: It must orbit a star (in our cosmic neighborhood, the Sun). Cookies help us deliver our Services. The star is more than 50 times as dense as the Sun. Don't know. Can a planet be bigger than its star? This thread is archived. A star of the aforementioned variety would theoretically be suitable enough to support a solar system as large or even larger than one like our own, but due to the circumstances surrounding its size, it would visually appear smaller than a planet like Jupiter despite being more massive. Anthony is a technology junkie that has vast experience in computer systems and automobile mechanics, as opposite as those sound. Yes! The short answer is “yes, it would be possible.” But as you might come to expect, the nitty-gritty details that make this statement true can become a bit more complicated than they seem and it has yet to be directly observed by astronomers today. Reactions: Labels: Astrum. Others think that it can only be a planet if it formed around a star. These two riddles above can be solved by reading this article. Coupled with other evidence of water i Regarding shape, stars appear as a dot while planets appear spherical. Answer Save. A moon orbits a planet. So I'm just wanting to know, is it theoretically possible for an extremely huge exoplanet to be larger than its extremely small host star? It is the source of light and heat. Our Sun is a star which is many times bigger than all of the planets. I've read that it is possible for a planet to be bigger than a star, but is it possible for a planet to be bigger than the star it orbits? Planets Jupiter-mass planets are about as large as a planet can get. A planet found in December 2009, GJ 1214 b, is 2.7 times as large as Earth and orbits a star much smaller and less luminous than our Sun. It is a dense object with a high surface gravity (300 gs according to the article at the end of the first link). A planet is a nearly spherical body which is in orbit around the Sun. You might be able to with a red dwarf but it would be a very low mass one with a planet the size of Jupiter or larger. He asked if an "extremely huge" planet can be large enough to be bigger than its star, which can't happen. Earth is about the size of an average sunspot! ...

This planet is thought to be at least twice as big as its star! I think you might be confusing two different processes here. Some moons can actually be smaller than some asteroids. The Very Large Telescope (VLT) of the European Southern Observatory (ESO), an array of four individual telescopes in the A smaller body always orbits around a larger body rather than the other way around because the larger body has more gravity. He asked if an "extremely huge" planet can be large enough to be bigger than its star, which can't happen. People are picking holes in this and I believe the premise is focusing on what we usually think of as main sequence stars, in which case, no they cannot. This suggests main sequence stars may be smaller in radius than gas giants, but this doesn't mean tiny stars will have gas giants orbiting them. The star Betelgeuse is a red supergiant star. One of the smallest known red dwarfs is EBLM J0555-57Ab, which is smaller than Jupiter. EDIT: After I posted this I saw u/jawhitten mentioned this M-dwarf. They have a diameter over 1,500 times bigger than the Sun. This can be very big objects as internal pressure from the reactions in the core keeps the radius large. https://en.wikipedia.org/wiki/EBLM_J0555-57#EBLM_J0555-57Ab. The mass and radius above come from Wikipedia article. 85 times as massive, to be exact. It will be quite some time before we can resolve a first generation star. This bending causes the star to appear to twinkle. Somebody else already mentioned the star EBLM J0555-57Ab, which has a radius only slightly in excess of that of Saturn (and less than that of Jupiter), https://earthsky.org/space/discovery-smallest-star-eblm-j0555-57ab. If Jupiter were much larger, pressure would be great enough to have fusion happen in its core, which is a star. To date, astronomers have catalogued over 1,000 exoplanets — some of them rocky and parked within their host star's habitable zone. Another tricky candidate for making this statement true are red or brown dwarf stars. If you could stand on the planet, the star would seem 60 times larger in diameter than the Sun does when we see it from Earth. I don't knwo about the telescope part tho. So can an asteroid be bigger than a planet? 1 decade ago. "This planet probably does have liquid water," said David Charbonneau, a Harvard professor of astronomy and lead author of an article on the discovery. Therefore no planet could ever be remotely close to the same mass as the sun. But, being denser, the planet could survive inside the giant star, and once the giant star became a planetary nebula + white dwarf core, the planet remained orbiting it every 1.4 days. I would disagree with this as you are talking about a white dwarf which is a stellar remnant rather than what we typically call a star. in most cases, a star is bigger than a planet. HR 5171 A is 50 per cent larger than the red hypergiant Betelgeuse , which is … If we consider neturon stars as stars then yes, a planet can be larger, but the star will remain the most massive. Since the planets are so much closer to the Earth than the stars, they appear larger to us. Edit: y'all downvoting this are missing the point of OP's question. in most cases, a star is bigger than a planet. Press J to jump to the feed. The sun is what we call a yellow dwarf star. If the Sun was a hypergiant star, it would reach out to as far as Jupiter. No. Just one handy quote: The Sun weighs about 333,000 times as much as Earth. The center of mass between the planet and the star would, I think, be outside of the star, because the star is so very small, but the same is true of our sun and Jupiter, and the latter is still thought of as being in orbit around the Sun, because it move so much more than the Sun does. Similar stories can be told about exoplanets residing in other stellar systems, where those stars can be hundreds of times larger than our Sun.
