Gliese 682 c is an exoplanet candidate believed to orbit the red dwarf Gliese 682. It is a super-Earth.
The planet has a mass of 4.4 ME and a radius of ~1.5 RE if rocky. Gliese 682 c was one of four planets discovered by researchers at the University of Hertfordshire and was discovered on March 4, 2014. The planet, at discovery, was the second-closest known planet in the so-called Goldilocks zone, at 17 light years.[2]
It orbits Gliese 682 at 0.176AU, in a nearly circular orbit each 57.3 days.[3]
A study in 2020 did not confirm the existence of Gliese 682 c, attributing radial velocity signal to the stellar activity instead.[4]
