TOI-6041 c
TOI-6041 c is a cold gas giant orbiting the G7 star TOI-6041 in the constellation Perseus. It lies about 236 light-years from Earth and was discovered in 2025 using the radial velocity method.
Is TOI-6041 c in the Habitable Zone?
TOI-6041 c orbits inside the inner edge of the habitable zone of TOI-6041. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-6041: 0.599–1.425 AU (conservative: 0.759–1.351 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-6041 c
The equilibrium temperature of TOI-6041 c is about 404 K (130 °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. It receives 4.42 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on TOI-6041 c — one full orbit around TOI-6041 — lasts 88.0 Earth days, between the years of Mercury (88 days) and Earth (365 days). It orbits at an average distance of 0.372 AU — closer to its star than Mercury is to the Sun.
How Was TOI-6041 c Discovered?
TOI-6041 c was discovered in 2025 using the radial velocity method, with observations from Multiple Observatories.
The radial velocity method measures the subtle wobble of a star caused by the gravitational pull of an orbiting planet, visible as periodic shifts in the star's light spectrum. The size of the wobble reveals the planet's minimum mass.
How Far Away Is TOI-6041 c?
TOI-6041 c is 236.4 light-years (72.5 parsecs) from Earth. Light arriving here tonight left the planet around the year 1790. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 4,160,640 years to make the journey.
