About this world
TIC 279401253 b is a gas giant orbiting TIC 279401253, a yellow, Sun-like star 931 light-years from Earth. It is about 1 times the size of Jupiter and holds 6.1 Jupiter masses. It completes an orbit every 76.8 days at 0.37 AU from its star, closer than Mercury is to the Sun, on a strongly elongated orbit (e = 0.45).
Its equilibrium temperature is about 486 K (213 °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. TIC 279401253 has 2 known planets; the others are TIC 279401253 c.
