nu Oct A is 69.1 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this K1 IV star; the first was found in 2016 by radial velocity (University of Canterbury Mt John Observatory).
Fly there in 3Dnu Oct A b takes 402.4 days to go round its star once.
nu Oct A is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

nu Oct B has no spectral type listed, with a computed orbit. In 1976 it was 0.1″ from nu Oct A, at position angle 331° (Washington Double Star Catalog, 21415-7723 BLM 6): 2.1 AU on the sky at this distance. The true distance can only be larger.
| Planet | Year | Orbit | Radius | Mass | Found |
|---|---|---|---|---|---|
| nu Oct A b disputed | 402.4 days | 1.240 AU | 13.3 R⊕ estimated | 696.04 M⊕ | Radial Velocity, 2016 |
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.
