TOI-2114 b
TOI-2114 b is a hot Jupiter orbiting the F5 IV star TOI-2114 in the constellation Hercules. It lies about 1,037 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TOI-2114 b?
TOI-2114 b has a radius of 14.55 times that of Earth, or 1.30 times the radius of Jupiter. Its mass is 324 times that of Earth, giving it a density of 0.58 g/cm³ — closer to gas planets like Jupiter (1.33 g/cm³).
Is TOI-2114 b in the Habitable Zone?
TOI-2114 b orbits inside the inner edge of the habitable zone of TOI-2114. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-2114: 1.755–4.079 AU (conservative: 2.222–3.867 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-2114 b
The equilibrium temperature of TOI-2114 b is about 1,472 K (1,199 °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 1,130 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on TOI-2114 b — one full orbit around TOI-2114 — lasts 6.21 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.076 AU — closer to its star than Mercury is to the Sun. Its orbit is highly elliptical (eccentricity 0.47), swinging dramatically closer to and farther from its star.
How Was TOI-2114 b Discovered?
TOI-2114 b was discovered in 2026 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-2114 b?
TOI-2114 b is 1,036.7 light-years (317.8 parsecs) from Earth. Light arriving here tonight left the planet about 1,037 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 18,245,920 years to make the journey.

Frequently Asked Questions About TOI-2114 b
Is TOI-2114 b habitable?
No — TOI-2114 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TOI-2114 b?
TOI-2114 b is about 1,037 light-years from Earth in the constellation Hercules. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 18,245,920 years to get there.
How big is TOI-2114 b compared to Earth?
TOI-2114 b has 14.55 times the radius of Earth and about 324 times its mass.
How long is a year on TOI-2114 b?
One orbit around TOI-2114 takes 6.2 Earth days — short enough that 59 of its years would fit into one Earth year.
