About this world
HD 108341 b is a gas giant orbiting HD 108341, an orange dwarf (type K2V) 160 light-years from Earth. It is about 1.2 times the size of Jupiter (its size estimated from its mass) and holds 2.3 Jupiter masses. It completes an orbit every 3.09 years at 2 AU from its star, on a strongly elongated orbit (e = 0.85).
Its equilibrium temperature is about 155 K (−118 °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 2014 by radial velocity with La Silla Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum.
