TOI-2295 c
TOI-2295 c is a cold gas giant orbiting TOI-2295 in the constellation Draco. It lies about 412 light-years from Earth and was discovered in 2024 using the radial velocity method. It orbits within the habitable zone of its star — the region where liquid water could exist on a planet's surface.
Is TOI-2295 c in the Habitable Zone?
TOI-2295 c orbits inside the conservative habitable zone of TOI-2295 — the region where a rocky planet could sustain liquid water on its surface. This makes it one of the most interesting known exoplanets in the search for life.
Habitable zone of TOI-2295: 1.080–2.548 AU (conservative: 1.368–2.416 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-2295 c
The equilibrium temperature of TOI-2295 c is about 235 K (-38 °C) — well below freezing. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C.
Orbit and Year Length
A year on TOI-2295 c — one full orbit around TOI-2295 — lasts 966.5 Earth days, longer than an Earth year. It orbits at an average distance of 2.018 AU. Its orbit is mildly elliptical (eccentricity 0.19).
How Was TOI-2295 c Discovered?
TOI-2295 c was discovered in 2024 using the radial velocity method, with observations from Haute-Provence Observatory.
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-2295 c?
TOI-2295 c is 411.9 light-years (126.3 parsecs) from Earth. Light arriving here tonight left the planet around the year 1615. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 7,249,440 years to make the journey.

Frequently Asked Questions About TOI-2295 c
Is TOI-2295 c habitable?
TOI-2295 c orbits within the habitable zone of TOI-2295, the region where liquid water could exist on a planet's surface. It sits in the conservative habitable zone — the most promising region for habitability. Whether it is actually habitable depends on its atmosphere and composition, which remain unknown.
How far away is TOI-2295 c?
TOI-2295 c is about 412 light-years from Earth in the constellation Draco. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 7,249,440 years to get there.
How long is a year on TOI-2295 c?
One orbit around TOI-2295 takes 966.5 Earth days.
