About this world
BD-13 2130 b is a gas giant orbiting BD-13 2130, a giant star (type G5IV/V) 3.02 thousand light-years from Earth. It is about 1.1 times the size of Jupiter (its size estimated from its mass), with at least 9.8 Jupiter masses (a minimum, measured by radial velocity). It completes an orbit every 714 days at 1.7 AU from its star, on a strongly elongated orbit (e = 0.21).
Its equilibrium temperature is about 745 K (472 °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 2007 by radial velocity with La Silla Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum.
