TOI-4409 is 585 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this K star; the first was found in 2026 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DTOI-4409 b takes 92.5 days to go round its star once.
Where the archive gives only a period or only an orbit size, the other is worked out from Kepler’s third law with the star’s mass.

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 4,928 K, 0.27 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.52 to 0.94 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 585 years ago, around 1440.
