TOI-2485 b
TOI-2485 b is a hot Jupiter orbiting TOI-2485 in the constellation Boötes. It lies about 1,298 light-years from Earth and was discovered in 2024 using the transit method.
How Big Is TOI-2485 b?
TOI-2485 b has a radius of 12.14 times that of Earth, or 1.08 times the radius of Jupiter. Its mass is 767 times that of Earth, giving it a density of 2.36 g/cm³ — between that of rocky and gaseous planets.
Is TOI-2485 b in the Habitable Zone?
The position of TOI-2485 b relative to the habitable zone of TOI-2485 cannot be precisely determined from the available orbital data.
Temperature on TOI-2485 b
The equilibrium temperature of TOI-2485 b is about 1,134 K (861 °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 276 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on TOI-2485 b — one full orbit around TOI-2485 — lasts 11.2 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.109 AU — closer to its star than Mercury is to the Sun. Its orbit is nearly circular (eccentricity 0.034).
How Was TOI-2485 b Discovered?
TOI-2485 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-2485 b?
TOI-2485 b is 1,297.9 light-years (398.0 parsecs) from Earth. Light arriving here tonight left the planet about 1,298 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 22,843,040 years to make the journey.

Frequently Asked Questions About TOI-2485 b
Is TOI-2485 b habitable?
TOI-2485 b is not known to orbit within the habitable zone of TOI-2485, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is TOI-2485 b?
TOI-2485 b is about 1,298 light-years from Earth in the constellation Boötes. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 22,843,040 years to get there.
How big is TOI-2485 b compared to Earth?
TOI-2485 b has 12.14 times the radius of Earth and about 767 times its mass.
How long is a year on TOI-2485 b?
One orbit around TOI-2485 takes 11.2 Earth days — short enough that 33 of its years would fit into one Earth year.
