WASP-102 is 1,747 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this 5,990 K star; the first was found in 2025 by transit (SuperWASP).
Fly there in 3DWASP-102 b goes round its star every 2.71 days, 32 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.
