TOI-2071 b
TOI-2071 b is a mini-Neptune orbiting TOI-2071 in the constellation Draco. It lies about 754 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TOI-2071 b?
TOI-2071 b has a radius of 2.56 times that of Earth.
Is TOI-2071 b in the Habitable Zone?
The position of TOI-2071 b relative to the habitable zone of TOI-2071 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-2071: 0.748–1.763 AU (conservative: 0.947–1.671 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-2071 b — one full orbit around TOI-2071 — lasts 5.67 Earth days, shorter than Mercury's 88-day year.
How Was TOI-2071 b Discovered?
TOI-2071 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-2071 b?
TOI-2071 b is 754.4 light-years (231.3 parsecs) from Earth. Light arriving here tonight left the planet around the year 1272. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 13,277,440 years to make the journey.

Frequently Asked Questions About TOI-2071 b
Is TOI-2071 b habitable?
TOI-2071 b is not known to orbit within the habitable zone of TOI-2071, and as a mini-Neptune it is an unlikely candidate for life as we know it.
How far away is TOI-2071 b?
TOI-2071 b is about 754 light-years from Earth in the constellation Draco. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 13,277,440 years to get there.
How big is TOI-2071 b compared to Earth?
TOI-2071 b has 2.56 times the radius of Earth.
How long is a year on TOI-2071 b?
One orbit around TOI-2071 takes 5.7 Earth days — short enough that 64 of its years would fit into one Earth year.
