TOI-3364 b
TOI-3364 b is a hot Jupiter orbiting TOI-3364 in the constellation Vela. It lies about 906 light-years from Earth and was discovered in 2023 using the transit method.
How Big Is TOI-3364 b?
TOI-3364 b has a radius of 12.23 times that of Earth, or 1.09 times the radius of Jupiter. Its mass is 531 times that of Earth, giving it a density of 1.60 g/cm³ — closer to gas planets like Jupiter (1.33 g/cm³).
Is TOI-3364 b in the Habitable Zone?
TOI-3364 b orbits inside the inner edge of the habitable zone of TOI-3364. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-3364: 1.047–2.472 AU (conservative: 1.326–2.343 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-3364 b
The equilibrium temperature of TOI-3364 b is about 1,264 K (991 °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 425 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on TOI-3364 b — one full orbit around TOI-3364 — lasts 5.88 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.068 AU — closer to its star than Mercury is to the Sun.
How Was TOI-3364 b Discovered?
TOI-3364 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-3364 b?
TOI-3364 b is 906.4 light-years (277.9 parsecs) from Earth. Light arriving here tonight left the planet around the year 1120. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 15,952,640 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-3364 b scores 0.08, ranking #4,785 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About TOI-3364 b
Is TOI-3364 b habitable?
No — TOI-3364 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TOI-3364 b?
TOI-3364 b is about 906 light-years from Earth in the constellation Vela. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 15,952,640 years to get there.
How big is TOI-3364 b compared to Earth?
TOI-3364 b has 12.23 times the radius of Earth and about 531 times its mass.
How long is a year on TOI-3364 b?
One orbit around TOI-3364 takes 5.9 Earth days — short enough that 62 of its years would fit into one Earth year.
