The planets in detail
HR 810 b is a Neptune-like world with about 12.70 Earth radii and 1970.54 Earth masses. It orbits HR 810 at 0.9200 AU with a 303-day year, and no published equilibrium temperature. It was confirmed in 1999 via radial velocity (Doppler) measurements.
Discovery
The single planet in the HR 810 system was confirmed in 1999 using radial velocity (Doppler) measurements. Detection facilities: La Silla 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 40.6417°, declination -50.7993°. 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.
