C/1925 F1 Shajn-Comas Sola
more info
Comet C/1925 F1 was discovered on 22 March 1925, more than five months before perihelion passage, and was last seen on 4 March 1927 [Kronk, Cometography: Volume 3].
This comet made its closest approach to the Earth on 25 March 1925 (3.42 au), that is about three days after its discovery; it has second close approach to the Earth on 27 January 1926 (3.48 au).
Solution given here is based on data spanning over 1.95 yr in a range of heliocentric distances from 4.41 au through perihelion (4.18 au) to 6.07 au.
This Oort spike comet suffers slight planetary perturbations during its passage through the planetary system that lead to a slightly more tight future orbit in comparison to original one.
