TIC 249022743 b
TIC 249022743 b is a Neptune-like planet orbiting TIC 249022743 in the constellation Orion. It lies about 1,293 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TIC 249022743 b?
TIC 249022743 b has a radius of 4.80 times that of Earth.
Is TIC 249022743 b in the Habitable Zone?
The position of TIC 249022743 b relative to the habitable zone of TIC 249022743 cannot be precisely determined from the available orbital data.
Habitable zone of TIC 249022743: 0.853–2.021 AU (conservative: 1.080–1.916 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TIC 249022743 b — one full orbit around TIC 249022743 — lasts 2.26 Earth days, shorter than Mercury's 88-day year.
How Was TIC 249022743 b Discovered?
TIC 249022743 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 249022743 b?
TIC 249022743 b is 1,293.1 light-years (396.5 parsecs) from Earth. Light arriving here tonight left the planet about 1,293 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 22,758,560 years to make the journey.
