HD 140901 is 49.7 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G7 IV star; the first was found in 2022 by radial velocity (Multiple Observatories).
Fly there in 3DHD 140901 b goes round its star every 9.02 days, 10 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.
