TIC 38828280 b
TIC 38828280 b is a mini-Neptune orbiting TIC 38828280 in the constellation Reticulum. It lies about 934 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TIC 38828280 b?
TIC 38828280 b has a radius of 2.63 times that of Earth.
Is TIC 38828280 b in the Habitable Zone?
The position of TIC 38828280 b relative to the habitable zone of TIC 38828280 cannot be precisely determined from the available orbital data.
Habitable zone of TIC 38828280: 0.442–1.066 AU (conservative: 0.560–1.011 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TIC 38828280 b — one full orbit around TIC 38828280 — lasts 4.86 Earth days, shorter than Mercury's 88-day year.
How Was TIC 38828280 b Discovered?
TIC 38828280 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 38828280 b?
TIC 38828280 b is 934.2 light-years (286.4 parsecs) from Earth. Light arriving here tonight left the planet around the year 1092. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 16,441,920 years to make the journey.

Frequently Asked Questions About TIC 38828280 b
Is TIC 38828280 b habitable?
TIC 38828280 b is not known to orbit within the habitable zone of TIC 38828280, and as a mini-Neptune it is an unlikely candidate for life as we know it.
How far away is TIC 38828280 b?
TIC 38828280 b is about 934 light-years from Earth in the constellation Reticulum. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 16,441,920 years to get there.
How big is TIC 38828280 b compared to Earth?
TIC 38828280 b has 2.63 times the radius of Earth.
How long is a year on TIC 38828280 b?
One orbit around TIC 38828280 takes 4.9 Earth days — short enough that 75 of its years would fit into one Earth year.
