The other star

WASP-94 B has no spectral type listed of magnitude 10.5, moving through space with it. In 2016 it was 15.1″ from WASP-94 A, at position angle 90° (Washington Double Star Catalog, 20551-3408 HJ 5234): 3,189 AU on the sky at this distance. The true distance can only be larger. Its colour is estimated from its brightness.

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.
