About this world
TYC 4282-00605-1 b is a gas giant orbiting TYC 4282-00605-1, a giant star 1.51 thousand light-years from Earth. It is about 1.1 times the size of Jupiter (its size estimated from its mass), with at least 11 Jupiter masses (a minimum, measured by radial velocity). It completes an orbit every 102 days at 0.42 AU from its star, on a strongly elongated orbit (e = 0.28).
Its equilibrium temperature is about 1,285 K (1,012 °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 2017 by radial velocity with Roque de los Muchachos Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum.
