TOI-6174 b
TOI-6174 b is a hot Jupiter orbiting TOI-6174 in the constellation Pegasus. It lies about 2,343 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TOI-6174 b?
TOI-6174 b has a radius of 7.83 times that of Earth, or 0.70 times the radius of Jupiter.
Is TOI-6174 b in the Habitable Zone?
The position of TOI-6174 b relative to the habitable zone of TOI-6174 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-6174: 0.890–2.105 AU (conservative: 1.127–1.996 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-6174 b — one full orbit around TOI-6174 — lasts 3.52 Earth days, shorter than Mercury's 88-day year.
How Was TOI-6174 b Discovered?
TOI-6174 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-6174 b?
TOI-6174 b is 2,342.9 light-years (718.3 parsecs) from Earth. Light arriving here tonight left the planet about 2,343 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 41,235,040 years to make the journey.

Frequently Asked Questions About TOI-6174 b
Is TOI-6174 b habitable?
TOI-6174 b is not known to orbit within the habitable zone of TOI-6174, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is TOI-6174 b?
TOI-6174 b is about 2,343 light-years from Earth in the constellation Pegasus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 41,235,040 years to get there.
How big is TOI-6174 b compared to Earth?
TOI-6174 b has 7.83 times the radius of Earth.
How long is a year on TOI-6174 b?
One orbit around TOI-6174 takes 3.5 Earth days — short enough that 104 of its years would fit into one Earth year.
