The planets in detail
eps Ind A b is a Neptune-like world with about 12.70 Earth radii and 2005.50 Earth masses. It orbits eps Ind A at 28.4000 AU with a 45.2-Earth-year orbit, and a temperate equilibrium temperature of 275 K. Its orbit is notably eccentric (e = 0.40), meaning the distance to its star — and the irradiation it receives — varies substantially over each year. It was confirmed in 2019 via radial velocity (Doppler) measurements.
Discovery
The single planet in the eps Ind A system was confirmed in 2019 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 330.8714°, declination -56.7969°. 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.
