This star is located about 224
AUs away on average (a semi-major axis of 14.39» at a HIPPARCOS distance of 50.87 light - years) with an orbital period around 2,000 years and an extremely high orbital eccentricity of 0.91.
Zeta1 has a brighter but distant stellar companion, Zeta2 Reticuli, currently located around 3,750
AUs away (based on an observed separation of 310» and HIPPARCOS distance estimates of 39.40 to 39.53 ly), with common proper motion and equal radial velocities (Da Silva and Foy, 1987).
The modelling suggested that a Neptune - like planet actually formed much closer to Vega and was pushed by a Jupiter - like planet in an inner orbit out to its current wide orbit around 80
AUs away from Vega over about 56 million years, sweeping many comets out with it and causing the dust disk to become clumpy (Mark C. Wyatt, 2003).
The distance separating Alpha Centauri A from its companion star B averages 23.7 AUs (of a semi-major axis), but swings between 11.4 and 36.0
AUs away in a highly elliptical orbit (e = 0.519) that takes almost 80 years to complete (see Dimitri Pourbaix, 2000 in the new Sixth Catalog of Orbits of Visual Binaries; Heintz Orbit Table, 12/1997; and Worley and Heintz, 1983).
The stars swings between 11.4 and 36.0
AUs away in a highly elliptical orbit (e = 0.52) that takes almost 80 (79.90) years to complete and are inclined at an angle of 79.23 ° from the perspective of an observer on Earth (see Pourbaix et al, 2002, or 2000 in the Sixth Catalog of Orbits of Visual Binaries; and Worley and Heintz, 1983).
Referred to as «extreme KBOs» (eKBOs) by the authors, all of these have extremely large orbital eccentricities, in other words, they get very close to the Sun at one point on their orbital journey, only to swing far out into space once they pass the Sun, on long elliptical orbits that take these strange mini worlds hundreds of
AUs away from the Sun.
