About this world
GJ 676 A c is a gas giant orbiting GJ 676 A, a cool red dwarf (type M0) 52.3 light-years from Earth. It is about 1.1 times the size of Jupiter (its size estimated from its mass) and holds 13 Jupiter masses. It completes an orbit every 38.1 years at 9.7 AU from its star, on a strongly elongated orbit (e = 0.29).
Its equilibrium temperature is about 48 K (−225 °C): too cold for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2016 by radial velocity with Paranal Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum. GJ 676 A has 4 known planets; the others are GJ 676 A d, GJ 676 A e and GJ 676 A b.
