BD-14 3065 b
BD-14 3065 b is a hot Jupiter orbiting BD-14 3065 A in the constellation Hydra. It lies about 1,922 light-years from Earth and was discovered in 2024 using the transit method.
How Big Is BD-14 3065 b?
BD-14 3065 b has a radius of 21.59 times that of Earth, or 1.93 times the radius of Jupiter. Its mass is 3,932 times that of Earth, giving it a density of 2.15 g/cm³ — between that of rocky and gaseous planets.
Is BD-14 3065 b in the Habitable Zone?
BD-14 3065 b orbits inside the inner edge of the habitable zone of BD-14 3065 A. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of BD-14 3065 A: 2.378–5.491 AU (conservative: 3.012–5.206 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on BD-14 3065 b
The equilibrium temperature of BD-14 3065 b is about 2,001 K (1,728 °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 BD-14 3065 b — one full orbit around BD-14 3065 A — lasts 4.29 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.066 AU — closer to its star than Mercury is to the Sun. Its orbit is mildly elliptical (eccentricity 0.07).
How Was BD-14 3065 b Discovered?
BD-14 3065 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 BD-14 3065 b?
BD-14 3065 b is 1,922.4 light-years (589.4 parsecs) from Earth. Light arriving here tonight left the planet about 1,922 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 33,834,240 years to make the journey.
The Host Star: BD-14 3065 A
BD-14 3065 b belongs to a system of 3 stars; it orbits BD-14 3065 A.

Frequently Asked Questions About BD-14 3065 b
Is BD-14 3065 b habitable?
No — BD-14 3065 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is BD-14 3065 b?
BD-14 3065 b is about 1,922 light-years from Earth in the constellation Hydra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 33,834,240 years to get there.
How big is BD-14 3065 b compared to Earth?
BD-14 3065 b has 21.59 times the radius of Earth and about 3,932 times its mass.
How long is a year on BD-14 3065 b?
One orbit around BD-14 3065 A takes 4.3 Earth days — short enough that 85 of its years would fit into one Earth year.
