47 UMa is 45.0 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this G0V star; the first was found in 1996 by radial velocity (Lick Observatory).
Fly there in 3D47 UMa d takes 38.3 years to go round its star once.

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.
