C/2016 KA Catalina
more info
Comet C/2016 KA was discovered on 16 May 2016 with Catalina Sky Survey, that is about 3.5 months after its perihelion passage. This comet was observed about three months until 3 April 2017.

Comet had its closest approach to the Earth on 2 June 2016 (5.240 au), about 4 months after its perihelion passage and about 2 weeks after its discovery.

The preferred solution given here is based on data spanning over 0.88 yr in a range of heliocentric distances from 5.46 au to 6.24 au.

This comet suffers insignificant planetary perturbations during its passage through the planetary system; have orignal and future semimajor axes shorter than 5000 au.
