WASP-140 is 384 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this K0 star; the first was found in 2016 by transit (SuperWASP-South).
Fly there in 3DWASP-140 b goes round its star every 2.24 days, 39 times as often as Mercury goes round the Sun.
WASP-140 is one of 2 stars in its system. The position of the other star is not catalogued, so only WASP-140 and its planets are drawn.

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.
