Resumen
BRANHAM JR., Richard L.. A new orbit for comet C/1865 B1 (Great southern comet of 1865). Rev. mex. astron. astrofis [online]. 2018, vol.54, n.1. ISSN 0185-1101.
Comet C/1865 B1 (Great southern comet of 1865), observed only in the southern hemisphere, is one of a large number of comets with parabolic orbits. Given that there are 202 observations in right ascension and 165 in declination it proves possible to calculate a better orbit than that Körber published in 1887, the orbit used in various catalogs and data bases. C/1865 B1’s orbit is hyperbolic and statistically distinguishable from a parabola. This object, therefore, cannot be considered an NEO. The comet has a small perihelion distance of 0.026 AU.
