SpaceExoplanets
Quick Answer
WASP-17b is one of the puffiest known exoplanets, with a radius larger than Jupiter’s despite having much less mass. It is an extreme hot Jupiter orbiting very close to its star.
The Full Story
WASP-17b is a famous example of an inflated hot Jupiter. It has a radius larger than Jupiter’s but only a fraction of Jupiter’s mass, giving it an unusually low density. The planet orbits its star very closely, which likely helps heat and inflate its atmosphere. Discoveries like this show that exoplanets can be far stranger than the giant planets in our Solar System.
