TIC 365102760 b
TIC 365102760 b is a hot Jupiter orbiting TIC 365102760 in the constellation Cygnus. It lies about 1,812 light-years from Earth and was discovered in 2024 using the transit method.
How Big Is TIC 365102760 b?
TIC 365102760 b has a radius of 6.21 times that of Earth, or 0.55 times the radius of Jupiter. Its mass is 19.2 times that of Earth, giving it a density of 0.44 g/cm³ — closer to gas planets like Jupiter (1.33 g/cm³).
Is TIC 365102760 b in the Habitable Zone?
TIC 365102760 b orbits inside the inner edge of the habitable zone of TIC 365102760. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TIC 365102760: 1.771–4.300 AU (conservative: 2.244–4.077 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TIC 365102760 b — one full orbit around TIC 365102760 — lasts 4.21 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.062 AU — closer to its star than Mercury is to the Sun. Its orbit is highly elliptical (eccentricity 0.41), swinging dramatically closer to and farther from its star.
How Was TIC 365102760 b Discovered?
TIC 365102760 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 365102760 b?
TIC 365102760 b is 1,811.9 light-years (555.5 parsecs) from Earth. Light arriving here tonight left the planet about 1,812 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 31,889,440 years to make the journey.

Frequently Asked Questions About TIC 365102760 b
Is TIC 365102760 b habitable?
No — TIC 365102760 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TIC 365102760 b?
TIC 365102760 b is about 1,812 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 31,889,440 years to get there.
How big is TIC 365102760 b compared to Earth?
TIC 365102760 b has 6.21 times the radius of Earth and about 19.2 times its mass.
How long is a year on TIC 365102760 b?
One orbit around TIC 365102760 takes 4.2 Earth days — short enough that 87 of its years would fit into one Earth year.
