WASP-178 is 1,395 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this A1 IV-V star; the first was found in 2019 by transit (WASP-South).
Fly there in 3DWASP-178 b goes round its star every 3.34 days, 26 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.
