K2-38 is 628 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G2 V star; the first was found in 2016 by transit (K2).
Fly there in 3DK2-38 b goes round its star every 4.02 days, 22 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.
