About this world
TIC 150070085 b is a sub-Neptune orbiting TIC 150070085, a yellow, Sun-like star 667 light-years from Earth. It is about 3.6 times the size of Earth. It completes an orbit every 10.5 days at 0.098 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 945 K (672 °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 2026 by transit with Transiting Exoplanet Survey Satellite (TESS). A planet crosses its star and dims it by a tiny, periodic fraction.
