The planets in detail
HD 110014 b is a Neptune-like world with about 12.40 Earth radii and 3524.59 Earth masses. It orbits HD 110014 at 2.1400 AU with a 2.3-Earth-year orbit, and no published equilibrium temperature. Its orbit is notably eccentric (e = 0.46), meaning the distance to its star — and the irradiation it receives — varies substantially over each year. It was confirmed in 2009 via radial velocity (Doppler) measurements.
Discovery
The single planet in the HD 110014 system was confirmed in 2009 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 189.8112°, declination -7.9957°. 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.
