Super-Jupiter

Makeup

By 2011 there were 180 known super-Jupiters, some hot, some cold. Even though they are more massive than Jupiter, they remain about the same size as Jupiter up to 80 Jupiter masses. An example of this may be the exoplanet HAT-P-1b with about half the mass of Jupiter but about 1.38 times larger diameter.

CoRoT-3b

CoRoT-3b, with a mass around 22 Jupiter masses, is predicted to have an average density of 26.4 g/cm3, greater than osmium (22.6 g/cm3), the densest natural element under standard conditions. Extreme compression of matter inside it causes the high density, because it is likely composed mainly of hydrogen. The surface gravity is also high, over 50 times that of Earth.

Kappa Andromedae b

In 2012, the super-Jupiter Kappa Andromedae b was imaged around the star Kappa Andromedae,
