The planets in detail
HD 62509 b is a Neptune-like world with about 13.30 Earth radii and 731.00 Earth masses. It orbits HD 62509 at 1.6400 AU with a 590-day year, and no published equilibrium temperature. It was confirmed in 2006 via radial velocity (Doppler) measurements.
Discovery
The single planet in the HD 62509 system was confirmed in 2006 using radial velocity (Doppler) measurements. Detection facilities: Multiple Observatories.
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 116.3288°, declination 28.0261°. 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.
