About this world

HD 52265 b is a gas giant orbiting HD 52265, a yellow, Sun-like star (type G0V) 97.8 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 119 days at 0.52 AU from its star, on a strongly elongated orbit (e = 0.27).

Its equilibrium temperature is about 405 K (132 °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 2000 by radial velocity with W. M. Keck Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum.
