TOI-6000 b
TOI-6000 b is a terrestrial planet orbiting TOI-6000 in the constellation Draco. It lies about 247 light-years from Earth and was discovered in 2025 using the transit method.
How Big Is TOI-6000 b?
TOI-6000 b has a radius of 0.94 times that of Earth.
Is TOI-6000 b in the Habitable Zone?
The position of TOI-6000 b relative to the habitable zone of TOI-6000 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-6000: 0.109–0.284 AU (conservative: 0.138–0.269 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-6000 b
The equilibrium temperature of TOI-6000 b is about 1,120 K (847 °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.
Orbit and Year Length
A year on TOI-6000 b — one full orbit around TOI-6000 — lasts just 10.8 hours, shorter than Mercury's 88-day year.
How Was TOI-6000 b Discovered?
TOI-6000 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-6000 b?
TOI-6000 b is 247.1 light-years (75.8 parsecs) from Earth. Light arriving here tonight left the planet around the year 1779. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 4,348,960 years to make the journey.

Frequently Asked Questions About TOI-6000 b
Is TOI-6000 b habitable?
TOI-6000 b is not known to orbit within the habitable zone of TOI-6000, and as a terrestrial planet it is an unlikely candidate for life as we know it.
How far away is TOI-6000 b?
TOI-6000 b is about 247 light-years from Earth in the constellation Draco. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 4,348,960 years to get there.
How big is TOI-6000 b compared to Earth?
TOI-6000 b has 0.94 times the radius of Earth.
How long is a year on TOI-6000 b?
One orbit around TOI-6000 takes 0.4 Earth days — short enough that 814 of its years would fit into one Earth year.
