Kepler-92

Planetary system · 1559.0 light-years away

Kepler-92 is 1,559 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this 5,883 K star; the first was found in 2013 by transit (Kepler).

Worth knowing

Kepler-92 b goes round its star every 13.7 days, 6 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 5,883 K, 3.6 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.80 to 3.16 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 1,559 years ago, around AD 470.
