HD 196067 is 130 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G0 V star; the first was found in 2012 by radial velocity (La Silla Observatory).
Fly there in 3DHD 196067 c goes round its star every 4.60 days, 19 times as often as Mercury goes round the Sun.
HD 196067 is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.
Where the archive gives only a period or only an orbit size, the other is worked out from Kepler’s third law with the star’s mass.
| Spectral type | G0 V |
| Surface temperature | 6,072 K |
| Mass | 1.16 solar masses |
| Radius | 1.71 solar radii |
| Luminosity | 3.54 times the Sun |
| Apparent magnitude | 6.51 |
| Age | about 4.2 billion years |
| Distance from the Sun | 130.3 light-years (39.9 parsecs) |

HD 196067 B has no spectral type listed of magnitude 7.07, moving through space with it. In 2023 it was 16.7″ from HD 196067, at position angle 20° (Washington Double Star Catalog, 20417-7521 DUN 232): 667 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 196067 c | 4.60 days | 0.0569 AU from Kepler’s law | 3.21 R⊕ estimated | 10.4 M⊕ minimum | Radial Velocity, 2025 |
| HD 196067 b | 9.3 years | 4.710 AU | 12.4 R⊕ estimated | 3623.2 M⊕ | Radial Velocity, 2012 |
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.
