TOI-682.01
TOI-682.01 is a sub-Neptune orbiting TOI-682 in the constellation Crater. It lies about 271 light-years from Earth and was discovered in 2021 using the transit method.
How Big Is TOI-682.01?
TOI-682.01 has a radius of 3.74 times that of Earth.
Is TOI-682.01 in the Habitable Zone?
The position of TOI-682.01 relative to the habitable zone of TOI-682 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-682: 0.652–1.572 AU (conservative: 0.826–1.491 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-682.01
The equilibrium temperature of TOI-682.01 is about 1,090 K (817 °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. It receives 234 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on TOI-682.01 — one full orbit around TOI-682 — lasts 6.84 Earth days, shorter than Mercury's 88-day year.
How Was TOI-682.01 Discovered?
TOI-682.01 was discovered in 2021 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-682.01?
TOI-682.01 is 271.2 light-years (83.2 parsecs) from Earth. Light arriving here tonight left the planet around the year 1755. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 4,773,120 years to make the journey.

Frequently Asked Questions About TOI-682.01
Is TOI-682.01 habitable?
TOI-682.01 is not known to orbit within the habitable zone of TOI-682, and as a sub-Neptune it is an unlikely candidate for life as we know it.
How far away is TOI-682.01?
TOI-682.01 is about 271 light-years from Earth in the constellation Crater. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 4,773,120 years to get there.
How big is TOI-682.01 compared to Earth?
TOI-682.01 has 3.74 times the radius of Earth.
How long is a year on TOI-682.01?
One orbit around TOI-682 takes 6.8 Earth days — short enough that 53 of its years would fit into one Earth year.
