TOI-5005 b
TOI-5005 b is a hot Jupiter orbiting the G2 V star TOI-5005 in the constellation Norma. It lies about 678 light-years from Earth and was discovered in 2024 using the transit method.
How Big Is TOI-5005 b?
TOI-5005 b has a radius of 6.25 times that of Earth, or 0.56 times the radius of Jupiter. Its mass is 32.7 times that of Earth, giving it a density of 0.74 g/cm³ — closer to gas planets like Jupiter (1.33 g/cm³).
Is TOI-5005 b in the Habitable Zone?
TOI-5005 b orbits inside the inner edge of the habitable zone of TOI-5005. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-5005: 0.692–1.632 AU (conservative: 0.877–1.547 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-5005 b
The equilibrium temperature of TOI-5005 b is about 1,040 K (767 °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 226 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on TOI-5005 b — one full orbit around TOI-5005 — lasts 6.31 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.066 AU — closer to its star than Mercury is to the Sun.
How Was TOI-5005 b Discovered?
TOI-5005 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-5005 b?
TOI-5005 b is 678.0 light-years (207.9 parsecs) from Earth. Light arriving here tonight left the planet around the year 1348. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 11,932,800 years to make the journey.

Frequently Asked Questions About TOI-5005 b
Is TOI-5005 b habitable?
No — TOI-5005 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TOI-5005 b?
TOI-5005 b is about 678 light-years from Earth in the constellation Norma. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 11,932,800 years to get there.
How big is TOI-5005 b compared to Earth?
TOI-5005 b has 6.25 times the radius of Earth and about 32.7 times its mass.
How long is a year on TOI-5005 b?
One orbit around TOI-5005 takes 6.3 Earth days — short enough that 58 of its years would fit into one Earth year.
