HD 10180 is 127 light-years from the Sun. The NASA Exoplanet Archive lists 6 planets around this G1 V star; the first was found in 2010 by radial velocity (La Silla Observatory).
Fly there in 3DHD 10180 c goes round its star every 5.76 days, 15 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.
For a star of 5,911 K, 1.5 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.15 to 2.02 AU. 1 of its 6 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.
The light you see left 127 years ago, around 1900.
