HD 107148 is 161 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G5 V star; the first was found in 2005 by radial velocity (W. M. Keck Observatory).
Fly there in 3DHD 107148 c goes round its star every 18.3 days, 5 times as often as Mercury goes round the Sun.
HD 107148 is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.
| Spectral type | G5 V |

HD 107148 B has no spectral type listed of magnitude 16.82, judged a true companion. In 2016 it was 35″ from HD 107148, at position angle 175° (Washington Double Star Catalog, 12192-0319 TOK 283): 1,730 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 107148 c | 18.3 days | 0.141 AU | 4.7 R⊕ estimated | 19.896 M⊕ minimum | Radial Velocity, 2021 |
| HD 107148 b | 48.1 days | 0.269 AU | 9.6 R⊕ estimated | 66.741 M⊕ minimum | Radial Velocity, 2005 |
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.
