HAT-P-12 is 466 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this K4 star; the first was found in 2009 by transit (HATNet).
Fly there in 3DHAT-P-12 b goes round its star every 3.21 days, 27 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.
