OGLE-2018-BLG-1011L is 23,157 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around it; the first was found in 2019 by microlensing (OGLE).
Fly there in 3DOGLE-2018-BLG-1011L c was found by microlensing: its star briefly magnified the light of a more distant one. That alignment happens once, so the planet cannot be watched again this way.
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.
