About this world
TIC 393818343 b is a gas giant orbiting TIC 393818343, a yellow, Sun-like star (type G0) 306 light-years from Earth. It is about 1.1 times the size of Jupiter and holds 4.3 Jupiter masses. It completes an orbit every 16.2 days at 0.13 AU from its star, closer than Mercury is to the Sun, on a strongly elongated orbit (e = 0.6).
Its equilibrium temperature is about 809 K (536 °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 2024 by transit with Transiting Exoplanet Survey Satellite (TESS). A planet crosses its star and dims it by a tiny, periodic fraction.
