HD 75784 is 279 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G5 star; the first was found in 2014 by radial velocity (W. M. Keck Observatory).
Fly there in 3DHD 75784 c takes 21.6 years to go round its star once.

| HD 75784 b | 341.2 days | 1.032 AU | 13.8 R⊕ estimated | 317.83 M⊕ minimum | Radial Velocity, 2014 |

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 4,867 K, 5.7 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 2.38 to 4.34 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.
