HAT-P-15 is 628 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this G5 star; the first was found in 2010 by transit (HATNet).
Fly there in 3DHAT-P-15 b goes round its star every 10.9 days, 8 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.
