Which known exoplanet is one of the largest by radius?
Quick Answer
WASP-17b is one of the puffiest known exoplanets, with a radius roughly twice that of Jupiter. Despite its huge size, it has very low density.
The Full Story
WASP-17b is among the largest known exoplanets by radius, measuring about twice Jupiter’s radius. Its density is extremely low because it is a bloated hot Jupiter orbiting very close to its star. The planet is so inflated that it has been a major target for atmospheric studies. Hot Jupiters like WASP-17b challenge theories of how gas giants form and evolve.
