About this world
HD 134060 c is a Neptune-like planet orbiting HD 134060, a yellow, Sun-like star (type G3IV) 78.3 light-years from Earth. It is about 5.9 times the size of Earth (its size estimated from its mass), with at least 29 Earth masses (a minimum, measured by radial velocity). It completes an orbit every 3.54 years at 2.4 AU from its star.
Its equilibrium temperature is about 201 K (−72 °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 2019 by radial velocity with La Silla Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum. HD 134060 has 2 known planets; the others are HD 134060 b.
