DMPP-4 is 82.6 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this F5-F8 V star; the first was found in 2023 by radial velocity (Multiple Observatories).
Fly there in 3DDMPP-4 b goes round its star every 3.50 days, 25 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 6,400 K, 2.9 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.55 to 2.70 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.
