TOI-2537 is 603 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this 4,870 K star; the first was found in 2024 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DTOI-2537 c takes 5.3 years to go round its star once.

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 4,870 K, 0.30 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.55 to 1.00 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 603 years ago, around 1420.
