HIP 12961 is 76.2 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this M0 star; the first was found in 2010 by radial velocity (La Silla Observatory).
Fly there in 3DHIP 12961 b goes round its star every 57.4 days, 1.5 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.
