Located less than 32 light-years from Earth, AU Microscopii is among the youngest planetary systems ever observed by astronomers, and its star throws vicious temper tantrums!
AU Microscopii b
Neptune-like
GJ 1132 b may have begun as a mini-Neptune, but is now a rocky world a little bigger than Earth. The planet may have lost one atmosphere but gained another from volcanic activity.
GJ 1132 b
Super Earth
GJ 15 A b orbits a red-dwarf star just 11 light-years away with its companion GJ 15 A c, making them our nearest multi-planet neighbors discovered so far.
GJ 15 A b
Super Earth
A giant planet composed mostly of gas. Also given the name Mulchatna, for a river in Alaska that supports indigenous and native populations.
HD 17156 b
Gas Giant
This far-off blue planet may look like a friendly haven – but don’t be deceived! Weather here is deadly. The planet’s cobalt blue color comes from a hazy, blow-torched atmosphere containing clouds laced with glass.

Kepler-16b is a world where two suns set over the horizon instead of just one, the first Tatooine-like planet found in our galaxy.
Kepler-16 b
Gas Giant
Kepler-186 f is a super Earth exoplanet that orbits an M-type star. Its mass is 1.71 Earths, it takes 129.9 days to complete one orbit of its star, and is 0.432 AU from its star. Its discovery was announced in 2014.

KELT-9b is so hot that the heat tears molecules apart on the dayside.

Kepler-16 b

A massive world called a hot Jupiter, Kepler-7b was the first exoplanet to have its clouds mapped.
Kepler-7 b
Gas Giant
Kepler-70b (a.k.a. KOI-55) could well be another circle of hell with an average temperature hotter than the Sun’s surface. It used to be Jupiter-sized until it spent some time inside its now-dead star…a trip that destroys most planets, but left this one a Freddy Krueger-like burned world smaller than Earth. At about 12,000 degrees F (6,800 C), it is one of the hottest planets discovered. In fact, the planet itself is evaporating, soon to be another victim.
