NGTS-24

Planetary system · 2227.9 light-years away

NGTS-24 is 2,228 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this G2 IV star; the first was found in 2022 by transit (Next-Generation Transit Survey (NGTS)).

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 5,820 K, 2.8 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.58 to 2.79 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 2,228 years ago, around 200 BC.
