Pair was listed, but in a "rejected" list, not part of discoverer's | ||
regular numbering sequence. | ||
AB Hyperbolic orbit by Hopmann (1960). e = 575. | Hop1960b | |
sigma = areal constant in the true orbit = 3.75 arcsec^2/yr | ||
q = periastron distance in the true orbit = 33".73 | ||
All hyperbolic orbits rejected from Fourth Orbit Catalog | Wor1983 | |
AC: Optical pair, based on study of relative motion of the components | ||
using the method of apparent motion parameters. | Kiy2008 |
