K2-219 is 1,061 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this 5,753 K star; the first was found in 2018 by transit (K2).
Fly there in 3DK2-219 b goes round its star every 3.90 days, 23 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.
