About this world
HD 192263 b is a gas giant orbiting HD 192263, an orange dwarf (type K2V) 64 light-years from Earth. It is about 1.3 times the size of Jupiter (its size estimated from its mass), with at least 0.56 Jupiter masses (a minimum, measured by radial velocity). It completes an orbit every 24.4 days at 0.15 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 486 K (213 °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 1999 by radial velocity with La Silla Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum.
