C/1914 M1 Neujmin
more info
Comet C/1914 M1 was discovered on 24 June 1914, about one month before perihelion passage, and was last seen on 10 August 1915 [Kronk, Cometography: Volume 3].
This comet made its closest approach to the Earth on 25 June 1914 (2.75 au), that is the next day after its discovery.
Solution given here is based on data spanning over 1.13 yr in a range of heliocentric distances from 3.76 au through perihelion (3.75 au) to 4.06 au.
This Oort spike comet suffers very slight planetary perturbations during its passage through the planetary system.
