HATS-24

Planetary system · 1611.8 light-years away

HATS-24 is 1,612 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this F V star; the first was found in 2017 by transit (HATSouth).

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 6,125 K, 1.5 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.16 to 2.03 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 1,612 years ago, around AD 410.
