Kepler-282

Planetary system · 4362.7 light-years away

Kepler-282 is 4,363 light-years from the Sun. The NASA Exoplanet Archive lists 4 planets around this 5,602 K star; the first was found in 2013 by transit (Kepler).

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 5,602 K, 1.3 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.09 to 1.92 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 4,363 years ago, around 2300 BC.
