TOI-1246 is 553 light-years from the Sun. The NASA Exoplanet Archive lists 4 planets around this K V star; the first was found in 2022 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DTOI-1246 b goes round its star every 4.31 days, 20 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.
