The planets in detail
nu Oct A b is a Neptune-like world with about 13.30 Earth radii and 696.04 Earth masses. It orbits nu Oct A at 1.2400 AU with a 402-day year, and no published equilibrium temperature. It was confirmed in 2016 via radial velocity (Doppler) measurements.
Discovery
The single planet in the nu Oct A system was confirmed in 2016 using radial velocity (Doppler) measurements. Detection facilities: University of Canterbury Mt John Observatory.
Observing from Earth
Exoplanets cannot be resolved visually with amateur telescopes — the host star's glare is overwhelming and even space-based direct imaging requires sophisticated coronagraphs. What you can observe is the host star itself at right ascension 325.3703°, declination -77.3911°. Use the 3D orrery above to inspect orbital geometry, planetary scale, and the habitable-zone overlay — the orbits are computed from the published Keplerian elements and animate at user-controlled time rates.
