Orbit and Year Length

A year on TIC 294329732 b — one full orbit around TIC 294329732 — lasts 9.76 Earth days, shorter than Mercury's 88-day year.

How Was TIC 294329732 b Discovered?

TIC 294329732 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 294329732 b?

TIC 294329732 b is 617.5 light-years (189.3 parsecs) from Earth. Light arriving here tonight left the planet around the year 1409. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 10,868,000 years to make the journey.

Frequently Asked Questions About TIC 294329732 b

Is TIC 294329732 b habitable?

TIC 294329732 b is not known to orbit within the habitable zone of TIC 294329732, and as a mini-Neptune it is an unlikely candidate for life as we know it.

How far away is TIC 294329732 b?

TIC 294329732 b is about 618 light-years from Earth in the constellation Carina. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 10,868,000 years to get there.

How big is TIC 294329732 b compared to Earth?

TIC 294329732 b has 2.08 times the radius of Earth.

How long is a year on TIC 294329732 b?

One orbit around TIC 294329732 takes 9.8 Earth days — short enough that 37 of its years would fit into one Earth year.
