TIC 219893931 b
TIC 219893931 b is a mini-Neptune orbiting TIC 219893931 in the constellation Draco. It lies about 1,339 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TIC 219893931 b?
TIC 219893931 b has a radius of 2.92 times that of Earth.
Is TIC 219893931 b in the Habitable Zone?
The position of TIC 219893931 b relative to the habitable zone of TIC 219893931 cannot be precisely determined from the available orbital data.
Habitable zone of TIC 219893931: 1.021–2.394 AU (conservative: 1.293–2.270 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TIC 219893931 b — one full orbit around TIC 219893931 — lasts 6.41 Earth days, shorter than Mercury's 88-day year.
How Was TIC 219893931 b Discovered?
TIC 219893931 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 219893931 b?
TIC 219893931 b is 1,338.7 light-years (410.5 parsecs) from Earth. Light arriving here tonight left the planet about 1,339 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 23,561,120 years to make the journey.

Frequently Asked Questions About TIC 219893931 b
Is TIC 219893931 b habitable?
TIC 219893931 b is not known to orbit within the habitable zone of TIC 219893931, and as a mini-Neptune it is an unlikely candidate for life as we know it.
How far away is TIC 219893931 b?
TIC 219893931 b is about 1,339 light-years from Earth in the constellation Draco. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 23,561,120 years to get there.
How big is TIC 219893931 b compared to Earth?
TIC 219893931 b has 2.92 times the radius of Earth.
How long is a year on TIC 219893931 b?
One orbit around TIC 219893931 takes 6.4 Earth days — short enough that 57 of its years would fit into one Earth year.
