PH1 is 3,370 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this F star; the first was found in 2012 by transit (Kepler).
Fly there in 3DPH1 b takes 138.3 days to go round its star once.
PH1 is one of 4 stars in its system. The position of the other 3 is not catalogued, so only PH1 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 6,407 K, 4.6 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.96 to 3.40 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.
