TOI-1732 b
TOI-1732 b is a mini-Neptune orbiting TOI-1732 in the constellation Lynx. It lies about 244 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TOI-1732 b?
TOI-1732 b has a radius of 2.50 times that of Earth.
Is TOI-1732 b in the Habitable Zone?
The position of TOI-1732 b relative to the habitable zone of TOI-1732 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-1732: 0.270–0.677 AU (conservative: 0.342–0.642 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-1732 b — one full orbit around TOI-1732 — lasts 4.12 Earth days, shorter than Mercury's 88-day year.
How Was TOI-1732 b Discovered?
TOI-1732 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-1732 b?
TOI-1732 b is 243.8 light-years (74.8 parsecs) from Earth. Light arriving here tonight left the planet around the year 1783. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 4,290,880 years to make the journey.

Frequently Asked Questions About TOI-1732 b
Is TOI-1732 b habitable?
TOI-1732 b is not known to orbit within the habitable zone of TOI-1732, and as a mini-Neptune it is an unlikely candidate for life as we know it.
How far away is TOI-1732 b?
TOI-1732 b is about 244 light-years from Earth in the constellation Lynx. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 4,290,880 years to get there.
How big is TOI-1732 b compared to Earth?
TOI-1732 b has 2.50 times the radius of Earth.
How long is a year on TOI-1732 b?
One orbit around TOI-1732 takes 4.1 Earth days — short enough that 89 of its years would fit into one Earth year.
