Kepler-149

Planetary system · 1862.5 light-years away

Kepler-149 is 1,863 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this 5,381 K star; the first was found in 2014 by transit (Kepler).

Worth knowing

Kepler-149 b goes round its star every 29.2 days, 3 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 5,381 K, 0.76 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.85 to 1.51 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 1,863 years ago, around AD 160.
