A Field Guide to Alien Planets

Hot Jupiter

A “Hot Jupiter” is a gas giant that is as close or closer to its star than Mercury is to our sun. The first discovery of an extrasolar planet around a sun-like star was 51 Pegasi B, an exoplanet roughly 50 light-years away. Of the 429 exoplanets discovered to date, 89 have been hot Jupiters, most likely because their large size and proximity to their stars makes them easier to spot using current techniques.
