The universe is full of fascinating objects, including planets, comets,
asteroids, stars more than 2,000 times the size of the Sun, and supermassive
black holes that have the power to rip celestial bodies apart.
It can be simpler to consider the nature of objects such as planets that are
nearby. Even though our Solar System is home to a number of large planets,
it makes sense to question if there are any larger planets out there. We are
looking at the largest planet in the universe because of this.
How large is this planet, where is it located, and how does it compare to
other planets in our neighborhood?
Join us as we explore the Largest Planet in the Universe discovered by
scientists.
We need a working definition to identify these celestial bodies even if the
answer to this issue may appear extremely straightforward.
The term “planet” has been given some fairly direct definitions. They’ll claim
that an accretion disk surrounding a star is what creates a planet. But that
doesn’t help us focus on the definition for a debate. Thankfully, we have a
regulating authority to provide us with the simple solution.
The International Astronomical Union defines a planet as having three
characteristics or having to perform three tasks:
It must move around a star. It must be substantial enough to be shaped
spherically by gravity. Its orbit around its star must be large enough for and
to pass through.
This definition caused controversy when it was first proposed because Pluto
was excluded from the list of planets in our Solar System. However, because
it excludes some celestial bodies from consideration, this definition is quite
useful.
The use of the term “exoplanet” must also be taken into account. An
exoplanet is, to put it simply, any planet outside of our Solar System.
And that leads us to AB Aur b, a massive exoplanet that resembles Jupiter.
This enormous planet, which is nine times the mass of Jupiter, was
discovered by scientists at an incredibly early stage of formation; they
describe it as still in the womb. This discovery casts doubt on the
conventional wisdom about how planets form.
The planet, a gas giant orbiting exceptionally far from its youthful host star,
was discovered and studied by scientists using the Hubble Space Telescope
in orbit and the Subaru Telescope near the peak of a dormant Hawaiian
volcano.
The largest planets in our solar system, Jupiter and Saturn, are examples of
gas giants. These planets are primarily made of hydrogen and helium, with
swirling gases encircling a smaller solid core.
This new research may hold the key to locating extraterrestrial life. “We
think it is still very early on in its ‘birthing’ process,” said astrophysicist
Thayne Currie of the Subaru Telescope and the NASA-Ames Research Center.
Evidence indicates that this is the earliest stage of gas giant creation ever
seen.
It is contained within a vast disk of gas and dust, which contains the
elements necessary to create planets, and which encircles the star AB
Aurigae, which is 508 light-years (or 9.5 trillion kilometers) away from Earth.
Exoplanets, or planets outside of our solar system, have been discovered in
about 5,000 instances. One among the largest is this one, AB Aur b. It is
getting close to the minimum size required to be categorized as a planet as
opposed to a brown dwarf, a body halfway between a planet and a star. It is
heated by gas and dust falling into it.
Nearly all exoplanets that are now known have orbits that are closer to their
stars than the distance between our solar and its furthest planet, Neptune.
However, this planet orbits the sun at a distance that is 93 times greater
than that of Earth and three times that of Neptune. The process of its
genesis seems to depart from the typical planetary formation hypothesis.
As stated by astronomer and study co-author Olivier Guyon of the Subaru
Telescope and the University of Arizona, “the conventional thinking is that
most, if not all, planets form by the slow accretion of solids onto a rocky
core, and that gas giants go through this phase before the solid core is
massive enough to start accreting gas.

Earth First!
See that's the thing, planets can only get to a certain size before they end up being different things. It's like the categorization between inches and feet, at a certain point they clearly become different things
This is mind blowing
As for requirement 3, *Earth*b has never cleared her orbit! There are many objects acting like moons that orbit our planet, cosmic junk whose nature changes over time as new objects are added and others wander away. Therefore Earth must be a dwarf planet, or not a planet at all. So much for the IAU. 😞
Pluto is still a planet….
why am i thinking now having listened ..that green energy reflected back at the sun is disrupting the photons?
9.5 trillion km is not 508 light years it's more like quadrillions of kilometers.
Enlightening thank you
those in heaven built it all, planets, suns, moons, etc. big as you want it.
How would anyone know that? The universe is massive. No way we can see all of it.
What about free floating planets not in orbit to a star, or planets in orbit to other larger planets?
Ideas are worthless unless we act on it
🤔🤔🤔
If there were a planet that size, it's gravity will need to be astronomical
It must control its surroundings other than its star, meaning it must not be controlled by other bodies' gravity, it must do the controlling.
I love this channel
PLUTONIUM LLUJMINUM URANIUM THORIUM OXYNL PLUTO PLANETOURIUME..
In the universe?
Take it easy there big guy.
God created all the heavenly bodies according to His will.
Does that count as a planet when its heavy enough to have nuclear fusion in the core?
God does beautifully, amazing work
If we could only construct the star trek enterprise and find captain kirk
So how many planets are flat like a pizza?? you know like the Earth is…😉
Update: a planet does not have to orbit a star. This update means, a planet launched from it's orbit does not change it's identity, it remains a planet… a lonely planet.
Even if this planet was habitable and if humans ever did reach there, they'd still fight for lands even when it'll be too large for even 1000000000 earthians💀
Pluto is a regular planet just because it's called dwarfs doesn't mean it's not a planet we call small people Dwarfs but they're still people
Have we EVER found a star that we belive may have formed during our life time ??
Gravitational accretion is wrong. It doesn't explain interstellar or intergalactic filaments, much less local planetary orbits.
Bet you any money there’s a few African and iraqi immigrants there already 💁🏻♂️
…as in the largest planet they know😌
Look are this smart person writing (Scientist Just Discovered The Largest Planet In The Universe)……. LOL….. Now let me ask you this. How do you know that? So they just discovered a larger Planet Ok great! But… How about if they discover another bigger than this one…. would you use the same Title? SMH….LOL Learn YouTuber you should write this for your title. (Scientist Just Discovered The Largest Planet In The Universe For Now). You don't know whats out there and if there is way bigger planet 10 times bigger than the previews one. And don't give an Age to anything from space either we don't know that -.-
Mira, esta persona inteligente está escribiendo (Científico acaba de descubrir el planeta más grande del universo)……. LOL….. Ahora déjame preguntarte esto. ¿Como sabes eso? Así que acaban de descubrir un Planeta más grande ¡Vale, genial! Pero… ¿Qué tal si descubren otro más grande que este…. usarías el mismo Título? SMH …. LOL Aprende YouTuber, debes escribir esto para tu título. (El científico acaba de descubrir el planeta más grande del universo por ahora). No sabes qué hay por ahí y si hay un planeta mucho más grande, 10 veces más grande que el de las vistas previas. Y no le des Edad a nada del espacio tampoco eso lo sabemos -.-
Just look at this check for $160.000 dollars ?You believe that too?
Give me the galaxies, baby. All day and night long. 🌙 🌅🎇🎆🌃🟡🟠
The largest planet in the universe…. so far..
Correct answer per Assistant Coach Luther Horatio Van Dam : I'll tell you what it says, "Dear Luther, I waited for you. You didn't come, so I've gone off to the Planet Arium".
Coach – S9:E10 Somewhere Out There (1997)
You ho a methane molecule and name it hydrogen.
Mercury only does 2 of the Requirements for a Planet…It DOES NOT Clear its orbit.
We as hairy monkeys, we think we have the rights to decide what Pluto can’t and can be it’s dumb we barely understand the creation of the universe and the destruction of the dinosaurs. And how were barley maintaining to be a civilization then we were 5,000 years ago, we’re no smarter then anything we just pull things out of our ass and name it, and call it what we want.
I've always thought planets are made from solar ejections, I have known this for decades
Hi 👋🌎✌️=💪***8888***
More we know about the universe, more we realize how infinite it is and how earth may be the only planet that sprung life that further created intelligent creatures like us.
I love listening to stuff like this but it just seems so unlikely. A bunch of material smaller than atoms gathered to form smaller pieces and those gathered to form larger pieces the size of sand and the those gathered etc etc… and from all that we got planets.
Then if you think of it just being gas then how does that form a solid? I guess.

But what would happen if Jupiter exploded
This is good stuff, though it's a little difficult to take it all in; when we look up at the stars we still feel the wonder that the first men felt.
Go back to the drawing board guys…

It just shows we have a lot more to learn about space bt start with earth first and spend the cash keeping it good for life !
Just perfect!
Probably not the largest in the universe. Just the largest you know of so far
