WASP-171 is 2,472 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this G0 star; the first was found in 2019 by transit (WASP-South).
Fly there in 3DWASP-171 b goes round its star every 3.82 days, 23 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 5,965 K, 4.7 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 2.04 to 3.57 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.
