About this world
HD 2952 b is a gas giant orbiting HD 2952, a giant star (type K0III) 359 light-years from Earth. It is about 1.2 times the size of Jupiter (its size estimated from its mass), with at least 0.9 Jupiter masses (a minimum, measured by radial velocity). It completes an orbit every 312 days at 1.1 AU from its star, on a strongly elongated orbit (e = 0.27).
Its equilibrium temperature is about 731 K (458 °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 2013 by radial velocity with Okayama Astrophysical Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum.
