TOI-4507 b
TOI-4507 b is a cold gas giant orbiting the F star TOI-4507 in the constellation Mensa. It lies about 581 light-years from Earth and was discovered in 2025 using the transit method.
How Big Is TOI-4507 b?
TOI-4507 b has a radius of 8.20 times that of Earth, or 0.73 times the radius of Jupiter. Its mass is 20.0 times that of Earth, giving it a density of 0.20 g/cm³ — closer to gas planets like Jupiter (1.33 g/cm³).
Is TOI-4507 b in the Habitable Zone?
TOI-4507 b orbits inside the inner edge of the habitable zone of TOI-4507. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-4507: 0.865–2.017 AU (conservative: 1.096–1.912 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-4507 b — one full orbit around TOI-4507 — lasts 104.6 Earth days, between the years of Mercury (88 days) and Earth (365 days). It orbits at an average distance of 0.456 AU — comparable to the inner Solar System. Its orbit is mildly elliptical (eccentricity 0.09).
How Was TOI-4507 b Discovered?
TOI-4507 b was discovered in 2025 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-4507 b?
TOI-4507 b is 581.4 light-years (178.3 parsecs) from Earth. Light arriving here tonight left the planet around the year 1445. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 10,232,640 years to make the journey.
