TOI-6662 b
TOI-6662 b is a terrestrial planet orbiting TOI-6662 in the constellation Camelopardalis. It lies about 69 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TOI-6662 b?
TOI-6662 b has a radius of 0.94 times that of Earth.
Is TOI-6662 b in the Habitable Zone?
The position of TOI-6662 b relative to the habitable zone of TOI-6662 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-6662: 0.092–0.241 AU (conservative: 0.117–0.228 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-6662 b — one full orbit around TOI-6662 — lasts just 7.1 hours, shorter than Mercury's 88-day year.
How Was TOI-6662 b Discovered?
TOI-6662 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-6662 b?
TOI-6662 b is 69.1 light-years (21.2 parsecs) from Earth. Light arriving here tonight left the planet around the year 1957. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 1,216,160 years to make the journey.

Frequently Asked Questions About TOI-6662 b
Is TOI-6662 b habitable?
TOI-6662 b is not known to orbit within the habitable zone of TOI-6662, and as a terrestrial planet it is an unlikely candidate for life as we know it.
How far away is TOI-6662 b?
TOI-6662 b is about 69 light-years from Earth in the constellation Camelopardalis. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 1,216,160 years to get there.
How big is TOI-6662 b compared to Earth?
TOI-6662 b has 0.94 times the radius of Earth.
How long is a year on TOI-6662 b?
One orbit around TOI-6662 takes 0.3 Earth days — short enough that 1,243 of its years would fit into one Earth year.
