About this world
HD 11343 c is a gas giant orbiting HIP 8541, a giant star (type K2III/I) 506 light-years from Earth. It is about 1.2 times the size of Jupiter (its size estimated from its mass), with at least 0.8 Jupiter masses (a minimum, measured by radial velocity). It completes an orbit every 229 days at 0.92 AU from its star.
Its equilibrium temperature is about 613 K (340 °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 2022 by radial velocity with Multiple Observatories. The star wobbles toward and away from us, Doppler-shifting its spectrum. HIP 8541 has 2 known planets; the others are HIP 8541 b.
