TOI-2211.01
TOI-2211.01 is a super-Earth orbiting TOI-2211 in the constellation Microscopium. It lies about 229 light-years from Earth and was discovered in 2024 using the transit method.
How Big Is TOI-2211.01?
TOI-2211.01 has a radius of 1.56 times that of Earth.
Is TOI-2211.01 in the Habitable Zone?
TOI-2211.01 orbits inside the inner edge of the habitable zone of TOI-2211. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-2211: 0.533–1.277 AU (conservative: 0.675–1.210 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-2211.01
TOI-2211.01 receives 296 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on TOI-2211.01 — one full orbit around TOI-2211 — lasts 3.09 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.040 AU — closer to its star than Mercury is to the Sun.
How Was TOI-2211.01 Discovered?
TOI-2211.01 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-2211.01?
TOI-2211.01 is 229.3 light-years (70.3 parsecs) from Earth. Light arriving here tonight left the planet around the year 1797. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 4,035,680 years to make the journey.

Frequently Asked Questions About TOI-2211.01
Is TOI-2211.01 habitable?
No — TOI-2211.01 orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TOI-2211.01?
TOI-2211.01 is about 229 light-years from Earth in the constellation Microscopium. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 4,035,680 years to get there.
How big is TOI-2211.01 compared to Earth?
TOI-2211.01 has 1.56 times the radius of Earth.
How long is a year on TOI-2211.01?
One orbit around TOI-2211 takes 3.1 Earth days — short enough that 118 of its years would fit into one Earth year.
