Kepler-432 is 2,766 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 4,995 K star; the first was found in 2015 by transit (Kepler).
Fly there in 3DKepler-432 b goes round its star every 52.5 days, 1.7 times as often as Mercury goes round the Sun.
Kepler-432 is one of 2 stars in its system. The position of the other star is not catalogued, so only Kepler-432 and its planets are drawn.
Where the archive gives only a period or only an orbit size, the other is worked out from Kepler’s third law with the star’s mass.

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.
