C/1974 F1 Lovas
more info
Comet C/1974 F1 was discovered on 22 February 1974 by Miklós Lovas (Budapest Observatory, Hungary), that is 1.5 years before its perihelion passage.
Comet had its closest approach to the Earth on 23 May 1975 (2.470 au), about 3 months before its perihelion passage.
Solutions given here are based on data spanning over 3.48 yr in a range of heliocentric distances: 5.64 au – 3.011 au (perihelion) – 7.26 au.
This Oort spike comet suffers moderate planetary perturbations during its passage through the planetary system; these perturbations lead to a more tight future orbit with semimajor axis of about 1,900 au.
