About this world
HD 130322 b is a gas giant orbiting HD 130322, an orange dwarf (type K0V) 104 light-years from Earth. It is about 1.2 times the size of Jupiter (its size estimated from its mass), with at least 1.2 Jupiter masses (a minimum, measured by radial velocity). It completes an orbit every 10.7 days at 0.092 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 720 K (447 °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 1999 by radial velocity with La Silla Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum.
