About this world
GJ 9714 b is a gas giant orbiting GJ 9714, an orange dwarf (type K5V) 66.9 light-years from Earth. It is about 1.1 times the size of Jupiter (its size estimated from its mass) and holds 9.4 Jupiter masses. It completes an orbit every 52.7 years at 12 AU from its star.
Its equilibrium temperature is about 48 K (−225 °C): too cold for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2022 by radial velocity with Multiple Observatories. The star wobbles toward and away from us, Doppler-shifting its spectrum.
