TIC 290487717 b
TIC 290487717 b is a hot Jupiter orbiting TIC 290487717 in the constellation Hydra. It lies about 1,290 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TIC 290487717 b?
TIC 290487717 b has a radius of 6.64 times that of Earth, or 0.59 times the radius of Jupiter.
Is TIC 290487717 b in the Habitable Zone?
The position of TIC 290487717 b relative to the habitable zone of TIC 290487717 cannot be precisely determined from the available orbital data.
Habitable zone of TIC 290487717: 0.618–1.477 AU (conservative: 0.783–1.400 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TIC 290487717 b — one full orbit around TIC 290487717 — lasts 3.40 Earth days, shorter than Mercury's 88-day year.
How Was TIC 290487717 b Discovered?
TIC 290487717 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 290487717 b?
TIC 290487717 b is 1,290.2 light-years (395.6 parsecs) from Earth. Light arriving here tonight left the planet about 1,290 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 22,707,520 years to make the journey.
