Answer 2

This is a very hard question to answer, as the over 99.999 of our universe is undiscovered. Right now, we think that HAT-P-1, a planet orbiting a distant star is the largest. It's roughly 1.4 times the size of our Solar System's largest planet Jupiter.

Answer 3

Jupiter is the largest planet in our solar system. In terms of exoplanets, there are some gas giants such as HD 100546 b and WASP-17b that are even larger. The universe is vast and there may be other planets yet to be discovered that could be even larger.
