HD 38529 is 138 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G4 IV star; the first was found in 2000 by radial velocity (Multiple Observatories).
Fly there in 3DHD 38529 b goes round its star every 14.3 days, 6 times as often as Mercury goes round the Sun.
HD 38529 is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

HD 38529 B is a M3V star of magnitude 13.36, moving through space with it. In 2015 it was 283.6″ from HD 38529, at position angle 305° (Washington Double Star Catalog, 05466+0110 RAG 1): 12,012 AU on the sky at this distance. The true distance can only be larger.
| Planet | Year | Orbit | Radius | Mass | Found |
|---|---|---|---|---|---|
| HD 38529 b | 14.3 days | 0.115 AU | 14.1 R⊕ estimated | 206.59 M⊕ minimum | Radial Velocity, 2000 |
| HD 38529 c | 5.8 years | 3.226 AU | 12.5 R⊕ estimated | 3299.1 M⊕ | Radial Velocity, 2000 |
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.
