About this world

TIC 237913194 b is a gas giant orbiting TIC 237913194, a yellow, Sun-like star (type G3) 998 light-years from Earth. It is about 1.1 times the size of Jupiter and holds 1.9 Jupiter masses. It completes an orbit every 15.2 days at 0.12 AU from its star, closer than Mercury is to the Sun, on a strongly elongated orbit (e = 0.57).

Its equilibrium temperature is about 974 K (701 °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 2020 by transit with Transiting Exoplanet Survey Satellite (TESS). A planet crosses its star and dims it by a tiny, periodic fraction.
