Kepler-1661 is 1,339 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this K star; the first was found in 2020 by transit (Kepler).
Fly there in 3DKepler-1661 b takes 175.1 days to go round its star once.
Kepler-1661 is one of 2 stars in its system. The position of the other star is not catalogued, so only Kepler-1661 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.
