About this world
HD 6061 b is a sub-Neptune orbiting HD 6061, a yellow, Sun-like star 221 light-years from Earth. It is about 2.4 times the size of Earth and holds 10 Earth masses. It completes an orbit every 5.25 days at 0.06 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 1,075 K (802 °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 2023 by transit with Transiting Exoplanet Survey Satellite (TESS). A planet crosses its star and dims it by a tiny, periodic fraction.
