TOI-2200 b
TOI-2200 b is a hot Jupiter orbiting TOI-2200 in the constellation Volans. It lies about 820 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TOI-2200 b?
TOI-2200 b has a radius of 6.96 times that of Earth, or 0.62 times the radius of Jupiter.
Is TOI-2200 b in the Habitable Zone?
The position of TOI-2200 b relative to the habitable zone of TOI-2200 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-2200: 0.491–1.185 AU (conservative: 0.622–1.123 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-2200 b — one full orbit around TOI-2200 — lasts 2.94 Earth days, shorter than Mercury's 88-day year.
How Was TOI-2200 b Discovered?
TOI-2200 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-2200 b?
TOI-2200 b is 819.5 light-years (251.2 parsecs) from Earth. Light arriving here tonight left the planet around the year 1207. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 14,423,200 years to make the journey.

Frequently Asked Questions About TOI-2200 b
Is TOI-2200 b habitable?
TOI-2200 b is not known to orbit within the habitable zone of TOI-2200, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is TOI-2200 b?
TOI-2200 b is about 820 light-years from Earth in the constellation Volans. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 14,423,200 years to get there.
How big is TOI-2200 b compared to Earth?
TOI-2200 b has 6.96 times the radius of Earth.
How long is a year on TOI-2200 b?
One orbit around TOI-2200 takes 2.9 Earth days — short enough that 124 of its years would fit into one Earth year.
