TIC 24750448 b
TIC 24750448 b is a mini-Neptune orbiting TIC 24750448 in the constellation Hydrus. It lies about 581 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TIC 24750448 b?
TIC 24750448 b has a radius of 2.44 times that of Earth.
Is TIC 24750448 b in the Habitable Zone?
The position of TIC 24750448 b relative to the habitable zone of TIC 24750448 cannot be precisely determined from the available orbital data.
Habitable zone of TIC 24750448: 0.353–0.869 AU (conservative: 0.447–0.824 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TIC 24750448 b — one full orbit around TIC 24750448 — lasts 3.59 Earth days, shorter than Mercury's 88-day year.
How Was TIC 24750448 b Discovered?
TIC 24750448 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 24750448 b?
TIC 24750448 b is 581.0 light-years (178.1 parsecs) from Earth. Light arriving here tonight left the planet around the year 1445. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 10,225,600 years to make the journey.

Frequently Asked Questions About TIC 24750448 b
Is TIC 24750448 b habitable?
TIC 24750448 b is not known to orbit within the habitable zone of TIC 24750448, and as a mini-Neptune it is an unlikely candidate for life as we know it.
How far away is TIC 24750448 b?
TIC 24750448 b is about 581 light-years from Earth in the constellation Hydrus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 10,225,600 years to get there.
How big is TIC 24750448 b compared to Earth?
TIC 24750448 b has 2.44 times the radius of Earth.
How long is a year on TIC 24750448 b?
One orbit around TIC 24750448 takes 3.6 Earth days — short enough that 102 of its years would fit into one Earth year.
