About this world
HD 80913 b is a gas giant orbiting HD 80913, a yellow-white F-type star 200 light-years from Earth. It is about 1.1 times the size of Jupiter (its size estimated from its mass) and holds 24 Jupiter masses. It completes an orbit every 29.7 years at 9.9 AU from its star, on a strongly elongated orbit (e = 0.31).
Its equilibrium temperature is about 118 K (−155 °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.
