About this world
HIP 70849 b is a gas giant orbiting HIP 70849, an orange dwarf (type K7V) 78.5 light-years from Earth. It is about 1.2 times the size of Jupiter (its size estimated from its mass) and holds 4.5 Jupiter masses. It completes an orbit every 9.99 years at 4 AU from its star, on a strongly elongated orbit (e = 0.65).
Its equilibrium temperature is about 79 K (−194 °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 2011 by radial velocity with La Silla Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum.
