TOI-4379 b
TOI-4379 b is a hot Jupiter orbiting TOI-4379 in the constellation Scorpius. It lies about 2,104 light-years from Earth and was discovered in 2024 using the transit method.
How Big Is TOI-4379 b?
TOI-4379 b has a radius of 16.69 times that of Earth, or 1.49 times the radius of Jupiter. Its mass is 354 times that of Earth.
Is TOI-4379 b in the Habitable Zone?
The position of TOI-4379 b relative to the habitable zone of TOI-4379 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-4379: 1.541–3.608 AU (conservative: 1.951–3.421 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-4379 b — one full orbit around TOI-4379 — lasts 3.25 Earth days, shorter than Mercury's 88-day year. Its orbit is nearly circular (eccentricity 0.018).
How Was TOI-4379 b Discovered?
TOI-4379 b was discovered in 2024 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-4379 b?
TOI-4379 b is 2,104.2 light-years (645.2 parsecs) from Earth. Light arriving here tonight left the planet about 2,104 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 37,033,920 years to make the journey.

Frequently Asked Questions About TOI-4379 b
Is TOI-4379 b habitable?
TOI-4379 b is not known to orbit within the habitable zone of TOI-4379, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is TOI-4379 b?
TOI-4379 b is about 2,104 light-years from Earth in the constellation Scorpius. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 37,033,920 years to get there.
How big is TOI-4379 b compared to Earth?
TOI-4379 b has 16.69 times the radius of Earth and about 354 times its mass.
How long is a year on TOI-4379 b?
One orbit around TOI-4379 takes 3.3 Earth days — short enough that 112 of its years would fit into one Earth year.
