TOI-4567 b
TOI-4567 b is a mini-Neptune orbiting TOI-4567 in the constellation Volans. It lies about 298 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TOI-4567 b?
TOI-4567 b has a radius of 2.33 times that of Earth.
Is TOI-4567 b in the Habitable Zone?
The position of TOI-4567 b relative to the habitable zone of TOI-4567 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-4567: 0.218–0.557 AU (conservative: 0.276–0.528 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-4567 b — one full orbit around TOI-4567 — lasts 23.5 Earth days, shorter than Mercury's 88-day year.
How Was TOI-4567 b Discovered?
TOI-4567 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-4567 b?
TOI-4567 b is 297.8 light-years (91.3 parsecs) from Earth. Light arriving here tonight left the planet around the year 1729. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 5,241,280 years to make the journey.

Frequently Asked Questions About TOI-4567 b
Is TOI-4567 b habitable?
TOI-4567 b is not known to orbit within the habitable zone of TOI-4567, and as a mini-Neptune it is an unlikely candidate for life as we know it.
How far away is TOI-4567 b?
TOI-4567 b is about 298 light-years from Earth in the constellation Volans. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 5,241,280 years to get there.
How big is TOI-4567 b compared to Earth?
TOI-4567 b has 2.33 times the radius of Earth.
How long is a year on TOI-4567 b?
One orbit around TOI-4567 takes 23.5 Earth days — short enough that 16 of its years would fit into one Earth year.
