TOI-4010 is 579 light-years from the Sun. The NASA Exoplanet Archive lists 4 planets around this K V star; the first was found in 2023 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DTOI-4010 b goes round its star every 32.4 hours, 65 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 4,960 K, 0.40 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.63 to 1.14 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.
The light you see left 579 years ago, around 1450.
