TOI-431 is 106 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this 4,850 K star; the first was found in 2021 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DTOI-431 b goes round its star every 11.8 hours, 180 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.
