Hot Neptune 热海王星

A hot Neptune is a type of giant planet with a mass similar to that of Uranus or Neptune in an orbit close to its star, normally less than 1 AU. The first hot Neptune to be discovered with certainty was Gliese 436 b in 2007, an exoplanet about 33 light years away. Recent observations have revealed a larger potential population of hot Neptunes in the Milky Way than previously thought.
