Name the largest planet in the universe.?

Answer 1

The largest diameter planet in the Universe will be about the size of Jupiter. The diameter is determined by physics. Less massive than Jupiter and the planet is smaller, and more massive and its own gravity tends to make it smaller.

The largest MASS planet will be about 20-60 times the mass of Jupiter. More massive than that and it will be considered a brown dwarf as it slowly fuses deuterium in its core. Where this cutoff sensibly belonds is still a subject of investigation. (see 2nd reference below)

Answer 2

Well, I don't think I can help you with the largest planet in the universe. There is no way of knowing something like that yet because the universe is so vast. But, the largest planet in our solar system is Jupiter, a gas giant.

Most of the other planets that have been discovered in the rest of the universe have been gas giants. Scientists have found over 150 extrasolar planets. The coolest thing is when they find a planet with a solid core (pretty rare). In July of 2005, Astrobiology printed this in an article:
"The planet, orbiting the sun-like star HD 149026, is roughly equal in mass to Saturn, but it is significantly smaller in diameter. It takes just 2.87 days to circle its star, and the upper atmosphere temperature is approximately 2,000 degrees Fahrenheit. Modeling of the planet's structure shows it has a solid core approximately 70 times Earth's mass." (http://www.astrobio.net/news/modules.php?op=modload&name=News&file=article&sid=1627&mode=thread&order=0&thold=0)

What makes this so cool is that it shows that it doesn't really matter how large the all of the extrasolar gas giant planets are, but if our theories on planet formation are right...if so, how many more solid core planets will we find and will any of them be inhabitated? Perhaps a new life form on another planet???

Answer 3

The largest planet in our solar system is Jupiter. The largest planet in the universe is Universal pictures...ha..ha

Answer 4

No one knows what the largest planet in the Universe is.

Answer 5

The largest of the known planets is Jupiter who knows if there is a larger one somewhere because we havent found it, yet.

Answer 6

The largest planet as we know it today is a gas giant similar to Jupiter.it is about 1.4 times larger,but has only about three fourths of jupiters mass,Hay-P-1 is located between lacerta,about 450 light-years (4.25723778 x 10^18 meters)from earth.the density of this gas giant is so low that it is less dense than a cork.

Answer 7

In the universe? We don't know. In our system? The Sol System (our star's name is Sol), the largest planet is Jupiter.

Answer 8

More than likely, due to the large amounts of space between planetary systems and the limitations of our observational methods, we cannot see enough of the universe to determine that even remotely for certain. There are billions of likely planetary systems that are not close enough for us to observe whether they even have planets or not. Do research into the size and proportions of the known universe and you will find this out.

Answer 9

the largest planet of the solar system is jupiter.it is 1600 times bigger than the earth.it also has the most gravitational force than any other planet in the solar system.

Answer 10

Jupiter
