TIC 4672985 b
TIC 4672985 b is a cold gas giant orbiting TIC 4672985 in the constellation Cetus. It lies about 826 light-years from Earth and was discovered in 2024 using the transit method.
How Big Is TIC 4672985 b?
TIC 4672985 b has a radius of 11.50 times that of Earth, or 1.03 times the radius of Jupiter. Its mass is 4,049 times that of Earth.
Is TIC 4672985 b in the Habitable Zone?
TIC 4672985 b orbits inside the inner edge of the habitable zone of TIC 4672985. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TIC 4672985: 0.857–2.020 AU (conservative: 1.085–1.915 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TIC 4672985 b
The equilibrium temperature of TIC 4672985 b is about 517 K (244 °C) — hotter than anywhere on Earth. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C.
Orbit and Year Length
A year on TIC 4672985 b — one full orbit around TIC 4672985 — lasts 69.0 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.330 AU — closer to its star than Mercury is to the Sun. Its orbit is nearly circular (eccentricity 0.018).
How Was TIC 4672985 b Discovered?
TIC 4672985 b was discovered in 2024 using the transit method, with observations from Transiting Exoplanet Survey Satellite (TESS).
The transit method watches a star for the tiny, regular dip in brightness that occurs when a planet crosses in front of it. The depth and timing of these dips reveal the planet's size and orbital period.
How Far Away Is TIC 4672985 b?
TIC 4672985 b is 826.4 light-years (253.4 parsecs) from Earth. Light arriving here tonight left the planet around the year 1200. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 14,544,640 years to make the journey.
