ups And is 43.7 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this F8 V star; the first was found in 1996 by radial velocity (Lick Observatory).
Fly there in 3Dups And b goes round its star every 4.62 days, 19 times as often as Mercury goes round the Sun.
ups And is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

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.
