HAT-P-22 is 267 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this G5 V star; the first was found in 2010 by transit (HATNet).
Fly there in 3DHAT-P-22 b goes round its star every 3.21 days, 27 times as often as Mercury goes round the Sun.
HAT-P-22 is one of 2 stars in its system. The position of the other star is not catalogued, so only HAT-P-22 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.
