TOI-1231 is 90.1 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this M3 V star; the first was found in 2021 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DTOI-1231 b goes round its star every 24.2 days, 4 times as often as Mercury goes round the Sun.

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.
