About this world
HD 47536 b is a gas giant orbiting HD 47536, a giant star (type K1III) 400 light-years from Earth. It is about 1.1 times the size of Jupiter (its size estimated from its mass), with at least 7.3 Jupiter masses (a minimum, measured by radial velocity). It completes an orbit every 712 days at 1.9 AU from its star.
Its equilibrium temperature is about 737 K (463 °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 2002 by radial velocity with La Silla Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum.
