HD 147513 is 42.1 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this G3/5V star; the first was found in 2003 by radial velocity (La Silla Observatory).
Fly there in 3DHD 147513 b takes 528.4 days to go round its star once.
HD 147513 is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

HD 147513 B is a DA12 star of magnitude 10.97, judged a true companion. In 2016 it was 345″ from HD 147513, at position angle 248° (Washington Double Star Catalog, 16240-3912 RAG 8): 4,452 AU on the sky at this distance. The true distance can only be larger.
| Planet | Year | Orbit | Radius | Mass | Found |

| HD 147513 b disputed | 528.4 days | 1.320 AU | 13.7 R⊕ estimated | 385 M⊕ minimum | Radial Velocity, 2003 |
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 5,883 K, 0.98 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.93 to 1.64 AU. Its one known planet 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.
