GJ 1252 is 66.4 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this M3 star; the first was found in 2020 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DGJ 1252 b goes round its star every 12.4 hours, 170 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.
