The planets in detail
HD 141004 b is a Mini-Neptune with about 3.77 Earth radii and 13.63 Earth masses. It orbits HD 141004 at 0.1238 AU with a 15.5-day year, and no published equilibrium temperature. It was confirmed in 2021 via radial velocity (Doppler) measurements.
Discovery
The single planet in the HD 141004 system was confirmed in 2021 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 236.6099°, declination 7.3528°. 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.
