TOI-1410.01
TOI-1410.01 is a sub-Neptune orbiting TOI-1410 in the constellation Lacerta. It lies about 237 light-years from Earth and was discovered in 2024 using the transit method.
How Big Is TOI-1410.01?
TOI-1410.01 has a radius of 3.10 times that of Earth. Its mass is 12.5 times that of Earth, giving it a density of 2.30 g/cm³ — between that of rocky and gaseous planets.
Is TOI-1410.01 in the Habitable Zone?
TOI-1410.01 orbits inside the inner edge of the habitable zone of TOI-1410. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-1410: 0.389–0.955 AU (conservative: 0.493–0.906 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-1410.01
The equilibrium temperature of TOI-1410.01 is about 1,237 K (964 °C) — hot enough to melt many metals. 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-1410.01 — one full orbit around TOI-1410 — lasts just 29.2 hours, shorter than Mercury's 88-day year. It orbits at an average distance of 0.021 AU — closer to its star than Mercury is to the Sun.
How Was TOI-1410.01 Discovered?
TOI-1410.01 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-1410.01?
TOI-1410.01 is 237.3 light-years (72.8 parsecs) from Earth. Light arriving here tonight left the planet around the year 1789. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 4,176,480 years to make the journey.

Frequently Asked Questions About TOI-1410.01
Is TOI-1410.01 habitable?
No — TOI-1410.01 orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TOI-1410.01?
TOI-1410.01 is about 237 light-years from Earth in the constellation Lacerta. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 4,176,480 years to get there.
How big is TOI-1410.01 compared to Earth?
TOI-1410.01 has 3.10 times the radius of Earth and about 12.5 times its mass.
How long is a year on TOI-1410.01?
One orbit around TOI-1410 takes 1.2 Earth days — short enough that 300 of its years would fit into one Earth year.
