HAT-P-7 is 1,113 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this F6 V star; the first was found in 2008 by transit (HATNet).
Fly there in 3DHAT-P-7 b goes round its star every 2.20 days, 40 times as often as Mercury goes round the Sun.
HAT-P-7 is one of 3 stars in its system. The position of the other 2 is not catalogued, so only HAT-P-7 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.
For a star of 6,389 K, 6.5 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 2.34 to 4.07 AU. None of its known planets orbits inside it. The zone says how much starlight arrives, not whether a planet has water or air. The edges follow Kopparapu et al. (2014), as the 3D view draws them.
