TOI-3714 b
TOI-3714 b is a hot Jupiter orbiting the M2 star TOI-3714 in the constellation Perseus. It lies about 368 light-years from Earth and was discovered in 2022 using the transit method.
How Big Is TOI-3714 b?
TOI-3714 b has a radius of 11.32 times that of Earth, or 1.01 times the radius of Jupiter. Its mass is 222 times that of Earth, giving it a density of 0.85 g/cm³ — closer to gas planets like Jupiter (1.33 g/cm³).
Is TOI-3714 b in the Habitable Zone?
TOI-3714 b orbits inside the inner edge of the habitable zone of TOI-3714. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-3714: 0.167–0.430 AU (conservative: 0.212–0.408 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-3714 b
The equilibrium temperature of TOI-3714 b is about 750 K (477 °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 54.00 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on TOI-3714 b — one full orbit around TOI-3714 — lasts 2.15 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.027 AU — closer to its star than Mercury is to the Sun. Its orbit is nearly circular (eccentricity 0.030).
How Was TOI-3714 b Discovered?
TOI-3714 b was discovered in 2022 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-3714 b?
TOI-3714 b is 367.6 light-years (112.7 parsecs) from Earth. Light arriving here tonight left the planet around the year 1659. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 6,469,760 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-3714 b scores 0.10, ranking #4,455 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About TOI-3714 b
Is TOI-3714 b habitable?
No — TOI-3714 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TOI-3714 b?
TOI-3714 b is about 368 light-years from Earth in the constellation Perseus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 6,469,760 years to get there.
How big is TOI-3714 b compared to Earth?
TOI-3714 b has 11.32 times the radius of Earth and about 222 times its mass.
How long is a year on TOI-3714 b?
One orbit around TOI-3714 takes 2.2 Earth days — short enough that 170 of its years would fit into one Earth year.
