Answer 3

Jupiter is the largest planet in our Solar System

As of 2007:

XO-3b The planet has a radius of 1.92 times Jupiter, the largest of any known extra-solar planets.

TrES-4 Has the largest diameter but is very rarefied so weighs very little.
Jupiter. Some say that the Sun makes up 99.9% of the mass in our solar system and Jupiter is another 0.05%. That means the remaining 0.05%, which is everything else, is only as massive as Jupiter when it's all combined.
If you mean it on solar system it is Jupiter. :)

I think largest planet known in whole universe is 11 Ursae Minoris b .

May be new one found May be it would help
