K2-395 is 935 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this K0 star; the first was found in 2022 by transit (K2).
Fly there in 3DK2-395 b goes round its star every 4.80 days, 18 times as often as Mercury goes round the Sun.
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.
