What is the largest planet in the galaxy?

Answer 1

The largest known planet so far seems to be Wasp-17b with a diameter 249,000km about twice that of Jupiter but significantly lower mass.

Wasp-17b's average density has been likened to that of a polystyrene cup due to its extremely low value.

HAT-P-32b is another larger potential candidate planet, however Wikipedia suggests that it might be a brown dwarf.
