TOI-5292 A

Planetary system · 1099.5 light-years away

TOI-5292 A is 1,100 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this M0±0.5 star; the first was found in 2026 by transit (Transiting Exoplanet Survey Satellite (TESS)).

Worth knowing

TOI-5292 A b goes round its star every 2.02 days, 44 times as often as Mercury goes round the Sun.

TOI-5292 A is one of 2 stars in its system. The position of the other star is not catalogued, so only TOI-5292 A and its planets are drawn.

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 3,919 K, 0.079 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.29 to 0.55 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 1,100 years ago, around AD 930.
