HIP 14810

Planetary system · 164.6 light-years away · also HIP 14810

HIP 14810 is 165 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this G5 star; the first was found in 2005 by radial velocity (W. M. Keck Observatory).

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 5,544 K, 0.98 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.95 to 1.69 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 165 years ago, around 1860.
