C/2010 U3 Boattini
more info
Comet C/2010 U3 was discovered on 31 October 2010. Several prediscovery images of this comet were found: taken at Mauna Kea on 18 and 30 October 2006 and 5 November 2005. At the moment of discovery, it was more than 8 years before its perihelion passage (see figure). In August 2023, data arc extends up to 15 April 2023 and are available at MPC.
Solutions given here are based on data covered 26.1 yr in a range of heliocentric distances: 26.1 au – 5.131 au (perihelion) – 19.8 au.
Comet had its closest approach to the Earth on 27 January 2019 (7.929 au, one months before perihelion).
Solutions given here are based on a set of data spanning over by 15.36 yr in a range of heliocentric distances: 25.75 au au – 8.446 au (perihelion) – 9.52 au (June 2023).
Some signs of NG acceleration in the motion of this comet are seen.
This Oort spike comet suffers a small planetary perturbations during its passage through the planetary system.
