TOI-6002 b
TOI-6002 b is a super-Earth orbiting the M3.5+/-0.5 star TOI-6002 in the constellation Cygnus. It lies about 105 light-years from Earth and was discovered in 2024 using the transit method.
How Big Is TOI-6002 b?
TOI-6002 b has a radius of 1.65 times that of Earth.
Is TOI-6002 b in the Habitable Zone?
TOI-6002 b orbits inside the inner edge of the habitable zone of TOI-6002. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-6002: 0.063–0.165 AU (conservative: 0.079–0.156 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-6002 b
The equilibrium temperature of TOI-6002 b is about 321 K (48 °C) — in a range broadly comparable to Earth, whose equilibrium temperature is 255 K. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C. It receives 1.68 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on TOI-6002 b — one full orbit around TOI-6002 — lasts 10.9 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.057 AU — closer to its star than Mercury is to the Sun. Its orbit is mildly elliptical (eccentricity 0.15).
How Was TOI-6002 b Discovered?
TOI-6002 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 TOI-6002 b?
TOI-6002 b is 104.5 light-years (32.0 parsecs) from Earth. Light arriving here tonight left the planet around the year 1922. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 1,839,200 years to make the journey.

Frequently Asked Questions About TOI-6002 b
Is TOI-6002 b habitable?
No — TOI-6002 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TOI-6002 b?
TOI-6002 b is about 105 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 1,839,200 years to get there.
How big is TOI-6002 b compared to Earth?
TOI-6002 b has 1.65 times the radius of Earth.
How long is a year on TOI-6002 b?
One orbit around TOI-6002 takes 10.9 Earth days — short enough that 33 of its years would fit into one Earth year.
