HIP 38594 is 58.0 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this M0 star; the first was found in 2020 by radial velocity (Multiple Observatories).
Fly there in 3DHIP 38594 b goes round its star every 60.7 days, 1.4 times as often as Mercury goes round the Sun.
HIP 38594 is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

HIP 38594 B is a DC star of magnitude 16.3, judged a true companion. In 2016 it was 399.8″ from HIP 38594, at position angle 209° (Washington Double Star Catalog, 07542-2518 SUB 3): 7,112 AU on the sky at this distance. The true distance can only be larger.
| Planet | Year | Orbit | Radius | Mass | Found |
|---|---|---|---|---|---|
| HIP 38594 b | 60.7 days | 0.256 AU | 2.77 R⊕ estimated | 8.1 M⊕ minimum | Radial Velocity, 2020 |

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.
