About this world
HIP 94235 b is a sub-Neptune orbiting HIP 94235, a yellow, Sun-like star (type GV) 191 light-years from Earth. It is about 3 times the size of Earth and holds 380 Earth masses. It completes an orbit every 7.71 days at 0.079 AU from its star, closer than Mercury is to the Sun, on a strongly elongated orbit (e = 0.32).
Its equilibrium temperature is about 1,060 K (787 °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 transit with Transiting Exoplanet Survey Satellite (TESS). A planet crosses its star and dims it by a tiny, periodic fraction.
