WASP-45 is 689 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this K2 V star; the first was found in 2011 by transit (SuperWASP).
Fly there in 3DWASP-45 b goes round its star every 3.13 days, 28 times as often as Mercury goes round the Sun.
WASP-45 is one of 2 stars in its system. The position of the other star is not catalogued, so only WASP-45 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.
