TOI-6130 b
TOI-6130 b is a hot Jupiter orbiting the F star TOI-6130 in the constellation Pegasus. It lies about 720 light-years from Earth and was discovered in 2024 using the transit method.
How Big Is TOI-6130 b?
TOI-6130 b has a radius of 14.35 times that of Earth, or 1.28 times the radius of Jupiter. Its mass is 334 times that of Earth, giving it a density of 0.64 g/cm³ — closer to gas planets like Jupiter (1.33 g/cm³).
Is TOI-6130 b in the Habitable Zone?
TOI-6130 b orbits inside the inner edge of the habitable zone of TOI-6130. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-6130: 1.250–2.923 AU (conservative: 1.584–2.771 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-6130 b
The equilibrium temperature of TOI-6130 b is about 1,750 K (1,477 °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 1,150 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on TOI-6130 b — one full orbit around TOI-6130 — lasts 2.39 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.036 AU — closer to its star than Mercury is to the Sun. Its orbit is nearly circular (eccentricity 0.036).
How Was TOI-6130 b Discovered?
TOI-6130 b was discovered in 2024 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-6130 b?
TOI-6130 b is 720.4 light-years (220.9 parsecs) from Earth. Light arriving here tonight left the planet around the year 1306. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 12,679,040 years to make the journey.

Frequently Asked Questions About TOI-6130 b
Is TOI-6130 b habitable?
No — TOI-6130 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TOI-6130 b?
TOI-6130 b is about 720 light-years from Earth in the constellation Pegasus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 12,679,040 years to get there.
How big is TOI-6130 b compared to Earth?
TOI-6130 b has 14.35 times the radius of Earth and about 334 times its mass.
How long is a year on TOI-6130 b?
One orbit around TOI-6130 takes 2.4 Earth days — short enough that 153 of its years would fit into one Earth year.
