BD+03 2562 b
BD+03 2562 b is a cold gas giant orbiting BD+03 2562 in the constellation Virgo. It lies about 3,492 light-years from Earth and was discovered in 2017 using the radial velocity method.
Is BD+03 2562 b in the Habitable Zone?
BD+03 2562 b orbits inside the inner edge of the habitable zone of BD+03 2562. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of BD+03 2562: 18.118–45.643 AU (conservative: 22.950–43.273 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on BD+03 2562 b — one full orbit around BD+03 2562 — lasts 481.9 Earth days, longer than an Earth year. It orbits at an average distance of 1.300 AU. Its orbit is mildly elliptical (eccentricity 0.20).
How Was BD+03 2562 b Discovered?
BD+03 2562 b was discovered in 2017 using the radial velocity method, with observations from Multiple Observatories.
The radial velocity method measures the subtle wobble of a star caused by the gravitational pull of an orbiting planet, visible as periodic shifts in the star's light spectrum. The size of the wobble reveals the planet's minimum mass.
How Far Away Is BD+03 2562 b?
BD+03 2562 b is 3,491.9 light-years (1,070.6 parsecs) from Earth. Light arriving here tonight left the planet about 3,492 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 61,457,440 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. BD+03 2562 b scores 0.07, ranking #4,835 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
