K2-29 is 582 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this G7 V star; the first was found in 2016 by transit (K2).
Fly there in 3DK2-29 b goes round its star every 3.26 days, 27 times as often as Mercury goes round the Sun.
K2-29 is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

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.
