TIC 147027702 b
TIC 147027702 b is a cold gas giant orbiting TIC 147027702 in the constellation Vela. It lies about 1,491 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TIC 147027702 b?
TIC 147027702 b has a radius of 10.93 times that of Earth, or 0.98 times the radius of Jupiter. Its mass is 346 times that of Earth, giving it a density of 1.57 g/cm³ — closer to gas planets like Jupiter (1.33 g/cm³).
Is TIC 147027702 b in the Habitable Zone?
TIC 147027702 b orbits inside the inner edge of the habitable zone of TIC 147027702. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TIC 147027702: 1.884–4.378 AU (conservative: 2.386–4.151 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TIC 147027702 b
The equilibrium temperature of TIC 147027702 b is about 863 K (590 °C) — hot enough to melt many metals. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C.
Orbit and Year Length
A year on TIC 147027702 b — one full orbit around TIC 147027702 — lasts 44.4 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.274 AU — closer to its star than Mercury is to the Sun. Its orbit is mildly elliptical (eccentricity 0.13).
How Was TIC 147027702 b Discovered?
TIC 147027702 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 147027702 b?
TIC 147027702 b is 1,491.1 light-years (457.2 parsecs) from Earth. Light arriving here tonight left the planet about 1,491 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 26,243,360 years to make the journey.
