TIC 245076932 b
TIC 245076932 b is a cold gas giant orbiting TIC 245076932 in the constellation Centaurus. It lies about 991 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TIC 245076932 b?
TIC 245076932 b has a radius of 10.87 times that of Earth, or 0.97 times the radius of Jupiter. Its mass is 162 times that of Earth, giving it a density of 0.75 g/cm³ — closer to gas planets like Jupiter (1.33 g/cm³).
Is TIC 245076932 b in the Habitable Zone?
TIC 245076932 b orbits inside the inner edge of the habitable zone of TIC 245076932. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TIC 245076932: 1.067–2.493 AU (conservative: 1.352–2.364 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TIC 245076932 b
The equilibrium temperature of TIC 245076932 b is about 845 K (572 °C) — hot enough to melt many metals. 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 245076932 b — one full orbit around TIC 245076932 — lasts 21.6 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.157 AU — closer to its star than Mercury is to the Sun. Its orbit is highly elliptical (eccentricity 0.43), swinging dramatically closer to and farther from its star.
How Was TIC 245076932 b Discovered?
TIC 245076932 b was discovered in 2026 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 245076932 b?
TIC 245076932 b is 991.4 light-years (304.0 parsecs) from Earth. Light arriving here tonight left the planet around the year 1035. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 17,448,640 years to make the journey.

Frequently Asked Questions About TIC 245076932 b
Is TIC 245076932 b habitable?
No — TIC 245076932 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TIC 245076932 b?
TIC 245076932 b is about 991 light-years from Earth in the constellation Centaurus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 17,448,640 years to get there.
How big is TIC 245076932 b compared to Earth?
TIC 245076932 b has 10.87 times the radius of Earth and about 162 times its mass.
How long is a year on TIC 245076932 b?
One orbit around TIC 245076932 takes 21.6 Earth days — short enough that 17 of its years would fit into one Earth year.
