Kepler-197 is 1,078 light-years from the Sun. The NASA Exoplanet Archive lists 4 planets around this 6,004 K star; the first was found in 2014 by transit (Kepler).
Fly there in 3DKepler-197 b goes round its star every 5.60 days, 16 times as often as Mercury goes round the Sun.
Kepler-197 is one of 2 stars in its system. The position of the other star is not catalogued, so only Kepler-197 and its planets are drawn.

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.
