TOI-480

Planetary system · 177.9 light-years away · also HIP 27849

TOI-480 is 178 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this 6,174 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 6,174 K, 2.9 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 2.76 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 178 years ago, around 1850.
