The planets in detail
ome Ser b is a Neptune-like world with about 14.00 Earth radii and 233.92 Earth masses. It orbits ome Ser at 0.8380 AU with a 279-day year, and no published equilibrium temperature. It was confirmed in 2013 via radial velocity (Doppler) measurements.
Discovery
The single planet in the ome Ser system was confirmed in 2013 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 237.5732°, declination 2.1963°. 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.
