TOI-3362 b
TOI-3362 b is a cold gas giant orbiting TOI-3362 in the constellation Vela. It lies about 1,197 light-years from Earth and was discovered in 2021 using the transit method.
How Big Is TOI-3362 b?
TOI-3362 b has a radius of 12.80 times that of Earth, or 1.14 times the radius of Jupiter. Its mass is 1,598 times that of Earth.
Is TOI-3362 b in the Habitable Zone?
TOI-3362 b orbits inside the inner edge of the habitable zone of TOI-3362. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-3362: 1.679–3.895 AU (conservative: 2.126–3.693 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-3362 b — one full orbit around TOI-3362 — lasts 18.1 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.153 AU — closer to its star than Mercury is to the Sun. Its orbit is highly elliptical (eccentricity 0.82), swinging dramatically closer to and farther from its star.
How Was TOI-3362 b Discovered?
TOI-3362 b 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-3362 b?
TOI-3362 b is 1,197.0 light-years (367.0 parsecs) from Earth. Light arriving here tonight left the planet about 1,197 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 21,067,200 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-3362 b scores 0.07, ranking #4,879 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About TOI-3362 b
Is TOI-3362 b habitable?
No — TOI-3362 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TOI-3362 b?
TOI-3362 b is about 1,197 light-years from Earth in the constellation Vela. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 21,067,200 years to get there.
How big is TOI-3362 b compared to Earth?
TOI-3362 b has 12.80 times the radius of Earth and about 1,598 times its mass.
How long is a year on TOI-3362 b?
One orbit around TOI-3362 takes 18.1 Earth days — short enough that 20 of its years would fit into one Earth year.
