About this world
TOI-7008 b is a Neptune-like planet orbiting TOI-7008, an orange dwarf 1.34 thousand light-years from Earth. It is about 4.9 times the size of Earth. It completes an orbit every 20.2 hours at 0.017 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 1,783 K (1,510 °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.
