TOI-7008 b
TOI-7008 b is a Neptune-like planet orbiting TOI-7008 in the constellation Ursa Minor. It lies about 1,339 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TOI-7008 b?
TOI-7008 b has a radius of 4.95 times that of Earth.
Is TOI-7008 b in the Habitable Zone?
The position of TOI-7008 b relative to the habitable zone of TOI-7008 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-7008: 0.582–1.400 AU (conservative: 0.737–1.327 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-7008 b — one full orbit around TOI-7008 — lasts just 20.2 hours, shorter than Mercury's 88-day year.
How Was TOI-7008 b Discovered?
TOI-7008 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-7008 b?
TOI-7008 b is 1,338.8 light-years (410.5 parsecs) from Earth. Light arriving here tonight left the planet about 1,339 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 23,562,880 years to make the journey.

Frequently Asked Questions About TOI-7008 b
Is TOI-7008 b habitable?
TOI-7008 b is not known to orbit within the habitable zone of TOI-7008, and as a Neptune-like planet it is an unlikely candidate for life as we know it.
How far away is TOI-7008 b?
TOI-7008 b is about 1,339 light-years from Earth in the constellation Ursa Minor. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 23,562,880 years to get there.
How big is TOI-7008 b compared to Earth?
TOI-7008 b has 4.95 times the radius of Earth.
How long is a year on TOI-7008 b?
One orbit around TOI-7008 takes 0.8 Earth days — short enough that 434 of its years would fit into one Earth year.
