KOI-4777 is 562 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this 3,515 K star; the first was found in 2022 by transit (Kepler).
Fly there in 3DKOI-4777.01 goes round its star every 9.9 hours, 214 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 3,515 K, 0.023 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.16 to 0.30 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.
