TOI-1811 is 418 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this 4,766 K star; the first was found in 2023 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DTOI-1811 b goes round its star every 3.71 days, 24 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.
