The planets in detail
HIP 107773 b is a Neptune-like world with about 13.40 Earth radii and 629.30 Earth masses. It orbits HIP 107773 at 0.7200 AU with a 144-day year, and no published equilibrium temperature. It was confirmed in 2015 via radial velocity (Doppler) measurements.
Discovery
The single planet in the HIP 107773 system was confirmed in 2015 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 327.5005°, declination -64.7127°. 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.
