TIC 237254473 b
TIC 237254473 b is a sub-Neptune orbiting TIC 237254473 in the constellation Draco. It lies about 1,326 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TIC 237254473 b?
TIC 237254473 b has a radius of 3.30 times that of Earth.
Is TIC 237254473 b in the Habitable Zone?
The position of TIC 237254473 b relative to the habitable zone of TIC 237254473 cannot be precisely determined from the available orbital data.
Habitable zone of TIC 237254473: 0.993–2.345 AU (conservative: 1.258–2.223 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TIC 237254473 b — one full orbit around TIC 237254473 — lasts 10.1 Earth days, shorter than Mercury's 88-day year.
How Was TIC 237254473 b Discovered?
TIC 237254473 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 237254473 b?
TIC 237254473 b is 1,326.3 light-years (406.6 parsecs) from Earth. Light arriving here tonight left the planet about 1,326 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 23,342,880 years to make the journey.

Frequently Asked Questions About TIC 237254473 b
Is TIC 237254473 b habitable?
TIC 237254473 b is not known to orbit within the habitable zone of TIC 237254473, and as a sub-Neptune it is an unlikely candidate for life as we know it.
How far away is TIC 237254473 b?
TIC 237254473 b is about 1,326 light-years from Earth in the constellation Draco. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 23,342,880 years to get there.
How big is TIC 237254473 b compared to Earth?
TIC 237254473 b has 3.30 times the radius of Earth.
How long is a year on TIC 237254473 b?
One orbit around TIC 237254473 takes 10.1 Earth days — short enough that 36 of its years would fit into one Earth year.
