WASP-12 is 1,394 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this 6,265 K star; the first was found in 2008 by transit (SuperWASP).
Fly there in 3DWASP-12 b goes round its star every 26.2 hours, 81 times as often as Mercury goes round the Sun.
WASP-12 is one of 3 stars in its system: the others are drawn where the Washington Double Star Catalog measures them on the sky.

WASP-12 B is a M3V star of magnitude 14.4, judged a true companion. In 2015 it was 1.1″ from WASP-12, at position angle 250° (Washington Double Star Catalog, 06305+2940 DAE 9 AB): 470 AU on the sky at this distance. The true distance can only be larger.
WASP-12 C is a M3V star of magnitude 14.4, judged a true companion. In 2013 it was 1.1″ from WASP-12, at position angle 247° (Washington Double Star Catalog, 06305+2940 BEC 1 AC): 470 AU on the sky at this distance. The true distance can only be larger.

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.
