C/1886 T1 Barnard-Hartwig
more info
C/1886 T1 was discovered on 5 October 1886 by Edward Emerson Barnard (Vanderbilt University Observatory, Nashville, Tennessee, USA). Independently, it was discovered on 6 October byErnst Hartwig (Bamberg Observatory, Germany). At the moment of discovery, the comet was about 2.5 months before its perihelion passage and was last seen on 17 June 1887 [Kronk, Cometography: Volume 2].
This comet made its closest approach to the Earth on 5 December 1886 (0.965 au), that is over 3 weeks after perihelion passage.
Solutions given here are based on data spanning over 0.693 yr in a range of heliocentric distances from 1.50 au through perihelion (0.663 au) to 3.01 au.
This Oort spike comet suffers tiny planetary perturbations during its passage through the planetary system; these perturbations lead to a little bit larger future semimajor axis (see future barycentric orbits).
C/1886 T1 was in the original sample of 19 comets used by Oort for his hypothesis on LPCs; however, according to presented here statistics for previous perihelion passage, dynamical status of this comet is uncertain.
