About this world
HD 179079 b is a gas giant orbiting HD 179079, a yellow, Sun-like star (type G5IV) 227 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 14.5 days at 0.12 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 998 K (724 °C): far too hot for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2008 by radial velocity with W. M. Keck Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum.
