TOI-1232 c
TOI-1232 c is a cold gas giant orbiting the G1 V star TOI-1232 in the constellation Carina. It lies about 1,072 light-years from Earth and was discovered in 2026 using the transit timing variations method.
Is TOI-1232 c in the Habitable Zone?
TOI-1232 c orbits inside the inner edge of the habitable zone of TOI-1232. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-1232: 0.814–1.916 AU (conservative: 1.031–1.816 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-1232 c — one full orbit around TOI-1232 — lasts 30.4 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.194 AU — closer to its star than Mercury is to the Sun. Its orbit is nearly circular (eccentricity 0.027).
How Was TOI-1232 c Discovered?
TOI-1232 c was discovered in 2026 using the transit timing variations method, with observations from Transiting Exoplanet Survey Satellite (TESS).
Transit timing variations reveal a planet through its gravitational tug on a sibling planet, which makes that sibling's transits arrive slightly early or late. The pattern of these deviations betrays the hidden planet's mass and orbit.
How Far Away Is TOI-1232 c?
TOI-1232 c is 1,071.8 light-years (328.6 parsecs) from Earth. Light arriving here tonight left the planet about 1,072 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 18,863,680 years to make the journey.

Frequently Asked Questions About TOI-1232 c
Is TOI-1232 c habitable?
No — TOI-1232 c orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TOI-1232 c?
TOI-1232 c is about 1,072 light-years from Earth in the constellation Carina. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 18,863,680 years to get there.
How long is a year on TOI-1232 c?
One orbit around TOI-1232 takes 30.4 Earth days — short enough that 12 of its years would fit into one Earth year.
