TOI-5486 b
TOI-5486 b is a sub-Neptune orbiting TOI-5486 in the constellation Virgo. It lies about 293 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TOI-5486 b?
TOI-5486 b has a radius of 3.97 times that of Earth.
Is TOI-5486 b in the Habitable Zone?
The position of TOI-5486 b relative to the habitable zone of TOI-5486 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-5486: 0.190–0.487 AU (conservative: 0.241–0.461 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-5486 b — one full orbit around TOI-5486 — lasts 2.02 Earth days, shorter than Mercury's 88-day year.
How Was TOI-5486 b Discovered?
TOI-5486 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-5486 b?
TOI-5486 b is 292.5 light-years (89.7 parsecs) from Earth. Light arriving here tonight left the planet around the year 1734. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 5,148,000 years to make the journey.

Frequently Asked Questions About TOI-5486 b
Is TOI-5486 b habitable?
TOI-5486 b is not known to orbit within the habitable zone of TOI-5486, and as a sub-Neptune it is an unlikely candidate for life as we know it.
How far away is TOI-5486 b?
TOI-5486 b is about 293 light-years from Earth in the constellation Virgo. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 5,148,000 years to get there.
How big is TOI-5486 b compared to Earth?
TOI-5486 b has 3.97 times the radius of Earth.
How long is a year on TOI-5486 b?
One orbit around TOI-5486 takes 2.0 Earth days — short enough that 180 of its years would fit into one Earth year.
