Kepler-181 is 1,987 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 5,333 K star; the first was found in 2014 by transit (Kepler).
Fly there in 3DKepler-181 b goes round its star every 3.14 days, 28 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.
