TIC 437041147 b
TIC 437041147 b is a mini-Neptune orbiting TIC 437041147 in the constellation Cancer. It lies about 804 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TIC 437041147 b?
TIC 437041147 b has a radius of 2.22 times that of Earth.
Is TIC 437041147 b in the Habitable Zone?
The position of TIC 437041147 b relative to the habitable zone of TIC 437041147 cannot be precisely determined from the available orbital data.
Habitable zone of TIC 437041147: 0.609–1.459 AU (conservative: 0.771–1.383 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TIC 437041147 b — one full orbit around TIC 437041147 — lasts 3.82 Earth days, shorter than Mercury's 88-day year.
How Was TIC 437041147 b Discovered?
TIC 437041147 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 TIC 437041147 b?
TIC 437041147 b is 804.3 light-years (246.6 parsecs) from Earth. Light arriving here tonight left the planet around the year 1222. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 14,155,680 years to make the journey.

Frequently Asked Questions About TIC 437041147 b
Is TIC 437041147 b habitable?
TIC 437041147 b is not known to orbit within the habitable zone of TIC 437041147, and as a mini-Neptune it is an unlikely candidate for life as we know it.
How far away is TIC 437041147 b?
TIC 437041147 b is about 804 light-years from Earth in the constellation Cancer. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 14,155,680 years to get there.
How big is TIC 437041147 b compared to Earth?
TIC 437041147 b has 2.22 times the radius of Earth.
How long is a year on TIC 437041147 b?
One orbit around TIC 437041147 takes 3.8 Earth days — short enough that 96 of its years would fit into one Earth year.
