TOI-3082 b
TOI-3082 b is a sub-Neptune orbiting TOI-3082 in the constellation Virgo. It lies about 369 light-years from Earth and was discovered in 2023 using the transit method.
How Big Is TOI-3082 b?
TOI-3082 b has a radius of 3.66 times that of Earth.
Is TOI-3082 b in the Habitable Zone?
The position of TOI-3082 b relative to the habitable zone of TOI-3082 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-3082: 0.300–0.750 AU (conservative: 0.380–0.711 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-3082 b
The equilibrium temperature of TOI-3082 b is about 1,033 K (760 °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-3082 b — one full orbit around TOI-3082 — lasts just 46.2 hours, shorter than Mercury's 88-day year.
How Was TOI-3082 b Discovered?
TOI-3082 b was discovered in 2023 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-3082 b?
TOI-3082 b is 368.7 light-years (113.0 parsecs) from Earth. Light arriving here tonight left the planet around the year 1658. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 6,489,120 years to make the journey.
Earth Similarity Index
The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. TOI-3082 b scores 0.19, ranking #3,953 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About TOI-3082 b
Is TOI-3082 b habitable?
TOI-3082 b is not known to orbit within the habitable zone of TOI-3082, and as a sub-Neptune it is an unlikely candidate for life as we know it.
How far away is TOI-3082 b?
TOI-3082 b is about 369 light-years from Earth in the constellation Virgo. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 6,489,120 years to get there.
How big is TOI-3082 b compared to Earth?
TOI-3082 b has 3.66 times the radius of Earth.
How long is a year on TOI-3082 b?
One orbit around TOI-3082 takes 1.9 Earth days — short enough that 190 of its years would fit into one Earth year.
