NGC 2682 Sand 1429 b
NGC 2682 Sand 1429 b is a cold gas giant orbiting the F9.5 V star NGC 2682 Sand 1429 in the constellation Cancer. It lies about 2,781 light-years from Earth and was discovered in 2024 using the radial velocity method.
Is NGC 2682 Sand 1429 b in the Habitable Zone?
NGC 2682 Sand 1429 b orbits inside the inner edge of the habitable zone of NGC 2682 Sand 1429. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of NGC 2682 Sand 1429: 1.701–3.985 AU (conservative: 2.154–3.778 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on NGC 2682 Sand 1429 b
The equilibrium temperature of NGC 2682 Sand 1429 b is about 683 K (410 °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 NGC 2682 Sand 1429 b — one full orbit around NGC 2682 Sand 1429 — lasts 77.5 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.384 AU — closer to its star than Mercury is to the Sun.
How Was NGC 2682 Sand 1429 b Discovered?
NGC 2682 Sand 1429 b was discovered in 2024 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 NGC 2682 Sand 1429 b?
NGC 2682 Sand 1429 b is 2,781.4 light-years (852.8 parsecs) from Earth. Light arriving here tonight left the planet about 2,781 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 48,952,640 years to make the journey.
