About this world
TIC 260969020 b is a sub-Neptune orbiting TIC 260969020, an orange dwarf 395 light-years from Earth. It is about 2.2 times the size of Earth. It completes an orbit every 8.49 days at 0.074 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 691 K (417 °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.
