TIC 241249530 b
TIC 241249530 b is a cold gas giant orbiting TIC 241249530 in the constellation Auriga. It lies about 1,058 light-years from Earth and was discovered in 2024 using the transit method.
How Big Is TIC 241249530 b?
TIC 241249530 b has a radius of 13.29 times that of Earth, or 1.19 times the radius of Jupiter. Its mass is 1,583 times that of Earth.
Is TIC 241249530 b in the Habitable Zone?
TIC 241249530 b orbits inside the inner edge of the habitable zone of TIC 241249530. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TIC 241249530: 1.173–2.738 AU (conservative: 1.485–2.596 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TIC 241249530 b — one full orbit around TIC 241249530 — lasts 165.8 Earth days, between the years of Mercury (88 days) and Earth (365 days). It orbits at an average distance of 0.641 AU — comparable to the inner Solar System. Its orbit is highly elliptical (eccentricity 0.94), swinging dramatically closer to and farther from its star.
How Was TIC 241249530 b Discovered?
TIC 241249530 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 241249530 b?
TIC 241249530 b is 1,058.2 light-years (324.4 parsecs) from Earth. Light arriving here tonight left the planet about 1,058 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 18,624,320 years to make the journey.
The Host Star: TIC 241249530
TIC 241249530 b belongs to a system of 2 stars; it orbits TIC 241249530.
