TOI-1269 c
TOI-1269 c is a mini-Neptune orbiting TOI-1269 in the constellation Draco. It lies about 561 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TOI-1269 c?
TOI-1269 c has a radius of 2.23 times that of Earth.
Is TOI-1269 c in the Habitable Zone?
The position of TOI-1269 c relative to the habitable zone of TOI-1269 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-1269: 0.592–1.407 AU (conservative: 0.750–1.334 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-1269 c — one full orbit around TOI-1269 — lasts 9.24 Earth days, shorter than Mercury's 88-day year.
How Was TOI-1269 c Discovered?
TOI-1269 c was discovered in 2026 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-1269 c?
TOI-1269 c is 561.4 light-years (172.1 parsecs) from Earth. Light arriving here tonight left the planet around the year 1465. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 9,880,640 years to make the journey.

Frequently Asked Questions About TOI-1269 c
Is TOI-1269 c habitable?
TOI-1269 c is not known to orbit within the habitable zone of TOI-1269, and as a mini-Neptune it is an unlikely candidate for life as we know it.
How far away is TOI-1269 c?
TOI-1269 c is about 561 light-years from Earth in the constellation Draco. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 9,880,640 years to get there.
How big is TOI-1269 c compared to Earth?
TOI-1269 c has 2.23 times the radius of Earth.
How long is a year on TOI-1269 c?
One orbit around TOI-1269 takes 9.2 Earth days — short enough that 40 of its years would fit into one Earth year.
