what is the largest planet in the universe?

Answer 1

Astronomers say they have discovered what appears to be an entirely new kind of planet, an extra-large gas giant unlike any known world in our solar system or beyond.

"This questions our understanding of how giant planets are formed and evolve," said Robert Noyes, a senior physicist at the Harvard-Smithsonian Center for Astrophysics (CfA).


The planet, dubbed HAT-P-1, is located some 450 light-years from Earth in the constellation Lacerta.

It is the largest planet ever discovered and boasts a radius nearly 1.4 times larger than Jupiter's.

HAT-P-1 is also the least dense of all known planets.

"This planet is about one quarter the density of water," said Gaspar Bakos, a Hubble fellow at CfA.

"In other words, it's lighter than a giant ball of cork. Just like Saturn, it would float in a bathtub if you could find a tub big enough to hold it, but it would float almost three times higher."

Unlike more familiar gas giants, including those in our solar system, HAT-P-1 does not appear to have a solid core.

Answer 2

Within our own solar system, the largest planet is Jupiter. There are exoplanets larger than Jupiter, the largest known one so far is HAT-P-1b which is 1.36 times wider than Jupiter. Exoplanet searching is still ongoing so there could be larger ones discovered in the future. Exoplanets can't get much larger than 13 Jupiter masses before they have some nuclear fusion and then they would be considered to be brown dwarf stars.

Answer 3

We have not cataloged all the planets in the universe. We have not cataloged all the planets in our galaxy. We do know that the largest planet in our star system is Jupiter.

Answer 4

It is a question which can be answere only when we have found all the planets in the universe!

Answer 5

I'm not sure. We've found many extrasolar planets that are insanely huge. Far bigger than Jupiter. It turns out that these huge planets are actually closer to the norm for planet formation.

Answer 6

The planet Gorbona in the star system Abdelabran, located near the galactic center of Andromeda.

Answer 7

Jupiter

Answer 8

Jupiter

Answer 9

That's impossible to say untill we discover all of them, I think that's a ways off.

Answer 10

hello friend, your question is not correct. because our scientific knowledge is very less. our scientific knowledge is sourroundings to sun's family only. so nobody can say answer to your question.
