EPIC 212624936

Planetary system · 1832.8 light-years away

EPIC 212624936 is 1,833 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 5,765 K star; the first was found in 2021 by transit (K2).

Worth knowing

EPIC 212624936 b goes round its star every 13.9 hours, 152 times as often as Mercury goes round the Sun.

Where the archive gives only a period or only an orbit size, the other is worked out from Kepler’s third law with the star’s mass.

Values are the NASA Exoplanet Archive’s composite parameters. A radius marked estimated comes from a mass–radius relation; a mass marked minimum is M sin i. Planet sizes and colours in the 3D view are renderings: none of these worlds has been photographed as more than a point of light.

The planets, compared

For a star of 5,765 K, 0.75 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.83 to 1.46 AU. None of its known planets orbits inside it. The zone says how much starlight arrives, not whether a planet has water or air. The edges follow Kopparapu et al. (2014), as the 3D view draws them.

The light you see left 1,833 years ago, around AD 190.
