## Super-earth around GJ 486

It is 1.29 times Earth's radius, closest in size to Earth, and 2.8 times Earth's mass, at 6.66 g/cm3, denser than Earth. A year there lasts 1.47 days, on an orbit 23 times closer to its star than Mercury is to the Sun. Its equilibrium temperature is 696 K, hotter than any desert. The host star GJ 486 runs at 3317 K with 0.31 times the Sun's mass.

What the wobble gives

The pull of the planet on its star, which is a lower bound on its mass.

Found by Calar Alto Observatory in 2021.

This planet was found by the wobble it induces in its star, which measures mass rather than size. A radius quoted for such a planet usually comes from a later transit or from a model.
