The planets in detail
HD 66141 b is a Neptune-like world with about 12.80 Earth radii and 1906.90 Earth masses. It orbits HD 66141 at 1.2000 AU with a 480-day year, and no published equilibrium temperature. It was confirmed in 2012 via radial velocity (Doppler) measurements.
Discovery
The single planet in the HD 66141 system was confirmed in 2012 using radial velocity (Doppler) measurements. Detection facilities: Bohyunsan Optical Astronomical 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 120.5663°, declination 2.3350°. 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.
