C/1902 R1 Perrine
more info
Comet C/1902 R1 was discovered on 1 September 1902 by Charles Dillon Perrine (Lick Observatory, California, USA), that is about three months before perihelion passage, and it was last seen on 28 April 1903 [Kronk, Cometography: Volume 3], however the last good quality measurements of its position was made on 31 March.
This comet made its closest approach to the Earth on 7 October 1902 (0.371 au), that is about five weeks after its discovery. At this time it was naked eye object.
Solution given here is based on data spanning over 0.578 yr in a range of heliocentric distances from 1.79 au through perihelion (0.401 au) to 2.44 au.
This Oort spike comet suffers moderate planetary perturbations during its passage through the planetary system that cause a more tight future orbit with semimajor axis of about 1150 au.
This comet was in the original sample of 19 comets used by Oort for his hypothesis on LPCs, and according to presented here statistics for previous perihelion passage, this comet most is dynamically new.
