We won't know the answer to that question until
1). We know that we've discovered every planet in the universe, and
2). We know the size of every planet that we've discovered.
Nobody knows what is the largest planet in the universe, but Jupiter is the largest planet in the Solar System.
The largest planet in the universe has not been identified, nor is it likely that a planet will ever be verified as the largest in the universe due to the immense volume of the universe. The largest known planets, however, are all gas giants, so it is reasonable to assume the largest planet in the universe would be largely comprised of Hydrogen and Helium gas, with heavier elements such as Iron and Nickel accounting for less than 15% of the planet's composition.

Earth is not the largest planet in the universe. I believe Jupiter is the largest planet in our solar system. If Jupiter is not the largest, Saturn is.

Jupiter is the largest planet in our solar system.
universe is vast subject . so up to now we don't no the entire universe. but up to the known information Jupiter is the largest planet but it does not occupies the largest space while revolving around the sun

Jupiter is the largest planet and Saturn is the second largest planet in our solar system.In the entire universe? Nobody knows -- there are literally trillions of planets.The second largest planet is Saturn. Saturn is the 6th planet from the sun about 885,904,700 miles.The 2nd planet orbiting the sun is Venus. Venus is 67,240,000 miles from the sun.

We don't have enough information about the universe to be able to know that. We do know, however, that the largest planet in our Solar system is Jupiter.
