TOI-6884 b
TOI-6884 b is a hot Jupiter orbiting TOI-6884 in the constellation Coma Berenices. It lies about 1,834 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TOI-6884 b?
TOI-6884 b has a radius of 10.39 times that of Earth, or 0.93 times the radius of Jupiter. Its mass is 8,365 times that of Earth, giving it a density of 41.00 g/cm³ — comparable to rocky planets like Earth (5.51 g/cm³).
Is TOI-6884 b in the Habitable Zone?
TOI-6884 b orbits inside the inner edge of the habitable zone of TOI-6884. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-6884: 1.608–3.743 AU (conservative: 2.037–3.549 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-6884 b
The equilibrium temperature of TOI-6884 b is about 1,652 K (1,379 °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. It receives 1,230 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on TOI-6884 b — one full orbit around TOI-6884 — lasts 4.81 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.063 AU — closer to its star than Mercury is to the Sun. Its orbit is mildly elliptical (eccentricity 0.07).
How Was TOI-6884 b Discovered?
TOI-6884 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 TOI-6884 b?
TOI-6884 b is 1,834.2 light-years (562.4 parsecs) from Earth. Light arriving here tonight left the planet about 1,834 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 32,281,920 years to make the journey.

Frequently Asked Questions About TOI-6884 b
Is TOI-6884 b habitable?
No — TOI-6884 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TOI-6884 b?
TOI-6884 b is about 1,834 light-years from Earth in the constellation Coma Berenices. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 32,281,920 years to get there.
How big is TOI-6884 b compared to Earth?
TOI-6884 b has 10.39 times the radius of Earth and about 8,365 times its mass.
How long is a year on TOI-6884 b?
One orbit around TOI-6884 takes 4.8 Earth days — short enough that 76 of its years would fit into one Earth year.
