TOI-1180

Planetary system · 234.9 light-years away · also TYC 4565-00656-1

TOI-1180 is 235 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this 4,738 K star; the first was found in 2024 by transit (Transiting Exoplanet Survey Satellite (TESS)).

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 4,738 K, 0.27 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.52 to 0.95 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 235 years ago, around 1790.
