The planets in detail
HD 196067 b is a Neptune-like world with about 12.40 Earth radii and 3623.24 Earth masses. It orbits HD 196067 at 4.7100 AU with a 9.3-Earth-year orbit, and no published equilibrium temperature. Its orbit is notably eccentric (e = 0.56), meaning the distance to its star — and the irradiation it receives — varies substantially over each year. It was confirmed in 2012 via radial velocity (Doppler) measurements.
HD 196067 c is a Mini-Neptune with about 3.21 Earth radii and 10.40 Earth masses. It orbits HD 196067 at an unknown distance with a 4.6-day year, and no published equilibrium temperature. Its orbit is notably eccentric (e = 0.23), meaning the distance to its star — and the irradiation it receives — varies substantially over each year. It was confirmed in 2025 via radial velocity (Doppler) measurements.
Discovery
The HD 196067 system was first identified in 2012, with confirmation work continuing through 2025 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 310.4364°, declination -75.3515°. 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.
