TOI-2669 b
TOI-2669 b is a hot Jupiter orbiting TOI-2669 in the constellation Hydra. It lies about 1,283 light-years from Earth and was discovered in 2022 using the transit method.
How Big Is TOI-2669 b?
TOI-2669 b has a radius of 19.73 times that of Earth, or 1.76 times the radius of Jupiter. Its mass is 194 times that of Earth.
Is TOI-2669 b in the Habitable Zone?
The position of TOI-2669 b relative to the habitable zone of TOI-2669 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-2669: 2.236–5.452 AU (conservative: 2.833–5.169 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-2669 b — one full orbit around TOI-2669 — lasts 6.20 Earth days, shorter than Mercury's 88-day year. Its orbit is mildly elliptical (eccentricity 0.09).
How Was TOI-2669 b Discovered?
TOI-2669 b was discovered in 2022 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 TOI-2669 b?
TOI-2669 b is 1,283.2 light-years (393.4 parsecs) from Earth. Light arriving here tonight left the planet about 1,283 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 22,584,320 years to make the journey.
Earth Similarity Index
The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. TOI-2669 b scores 0.05, ranking #5,298 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About TOI-2669 b
Is TOI-2669 b habitable?
TOI-2669 b is not known to orbit within the habitable zone of TOI-2669, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is TOI-2669 b?
TOI-2669 b is about 1,283 light-years from Earth in the constellation Hydra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 22,584,320 years to get there.
How big is TOI-2669 b compared to Earth?
TOI-2669 b has 19.73 times the radius of Earth and about 194 times its mass.
How long is a year on TOI-2669 b?
One orbit around TOI-2669 takes 6.2 Earth days — short enough that 59 of its years would fit into one Earth year.
