Kepler-430

Planetary system · 2992.4 light-years away

Kepler-430 is 2,992 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 5,884 K star; the first was found in 2015 by transit (Kepler).

Worth knowing

Kepler-430 b goes round its star every 36.0 days, 2.4 times as often as Mercury goes round the Sun.

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 5,884 K, 2.1 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.35 to 2.38 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 2,992 years ago, around 1000 BC.
