NGC 2682 YBP 401 b
NGC 2682 YBP 401 b is a hot Jupiter orbiting the F9 V star NGC 2682 YBP 401 in the constellation Cancer. It lies about 2,710 light-years from Earth and was discovered in 2016 using the radial velocity method.
Is NGC 2682 YBP 401 b in the Habitable Zone?
The position of NGC 2682 YBP 401 b relative to the habitable zone of NGC 2682 YBP 401 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on NGC 2682 YBP 401 b — one full orbit around NGC 2682 YBP 401 — lasts 4.09 Earth days, shorter than Mercury's 88-day year. Its orbit is mildly elliptical (eccentricity 0.15).
How Was NGC 2682 YBP 401 b Discovered?
NGC 2682 YBP 401 b was discovered in 2016 using the radial velocity method, with observations from La Silla Observatory.
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 NGC 2682 YBP 401 b?
NGC 2682 YBP 401 b is 2,709.8 light-years (830.8 parsecs) from Earth. Light arriving here tonight left the planet about 2,710 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 47,692,480 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. NGC 2682 YBP 401 b scores 0.06, ranking #5,065 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About NGC 2682 YBP 401 b
Is NGC 2682 YBP 401 b habitable?
NGC 2682 YBP 401 b is not known to orbit within the habitable zone of NGC 2682 YBP 401, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is NGC 2682 YBP 401 b?
NGC 2682 YBP 401 b is about 2,710 light-years from Earth in the constellation Cancer. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 47,692,480 years to get there.
How long is a year on NGC 2682 YBP 401 b?
One orbit around NGC 2682 YBP 401 takes 4.1 Earth days — short enough that 89 of its years would fit into one Earth year.
