The planets in detail
omi UMa b is a Neptune-like world with about 13.00 Earth radii and 1160.39 Earth masses. It orbits omi UMa at 3.6910 AU with a 4.3-Earth-year orbit, and no published equilibrium temperature. It was confirmed in 2012 via radial velocity (Doppler) measurements.
Discovery
The single planet in the omi UMa system was confirmed in 2012 using radial velocity (Doppler) measurements. Detection facilities: Okayama Astrophysical 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 127.5650°, declination 60.7177°. 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.
