HD 125612 is 188 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this G3 V star; the first was found in 2007 by radial velocity (W. M. Keck Observatory).
Fly there in 3DHD 125612 c goes round its star every 4.15 days, 21 times as often as Mercury goes round the Sun.
HD 125612 is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

HD 125612 B has no spectral type listed of magnitude 17.05, moving through space with it. In 2016 it was 90″ from HD 125612, at position angle 163° (Washington Double Star Catalog, 14209-1729 MUG 17): 5,186 AU on the sky at this distance. The true distance can only be larger. Its colour is estimated from its brightness.
| Planet | Year | Orbit | Radius | Mass | Found |
|---|---|---|---|---|---|
| HD 125612 c | 4.15 days | 0.0510 AU | 4.07 R⊕ estimated | 15.574 M⊕ minimum | Radial Velocity, 2009 |
| HD 125612 b | 557.7 days | 1.349 AU | 13.2 R⊕ estimated | 945.22 M⊕ minimum | Radial Velocity, 2007 |
| HD 125612 d | 7.7 years | 3.982 AU | 12.7 R⊕ estimated | 2281.4 M⊕ | Radial Velocity, 2009 |
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.
