GJ 687 is 14.8 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this M3.0V star; the first was found in 2014 by radial velocity (Lick Observatory).
Fly there in 3DGJ 687 b goes round its star every 38.1 days, 2.3 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.
