LHS 475 is 40.7 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this M3.5 V star; the first was found in 2023 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DLHS 475 b goes round its star every 2.03 days, 43 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 3,300 K, 0.0086 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.096 to 0.19 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.
