Kepler-396 is 730 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 5,656 K star; the first was found in 2013 by transit (Kepler).
Fly there in 3DKepler-396 b goes round its star every 43.0 days, 2.0 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.
