C/2011 J2 (LINEAR) is an Oort cloud comet discovered on 4 May 2011 by LINEAR at an apparent magnitude of 19.7 using a 1-meter (39 in ) Reflecting telescope .[1] [2] apparent magnitude 17.[3]
C/2011 J2 came to perihelion (closest approach to the Sun) on 25 December 2013 at a distance of 3.4 AU [3] [3] fragmentation event occurred around 14 July 2014 plus/minus ten days.[5]
Fragment C was detected in October 2014 by Ernesto Guido, Nick Howes, and Martino Nicolini.[6]
C/2011 J2 is dynamically new. It came from the Oort cloud with a loosely bound chaotic orbit that was easily perturbed by galactic tides and passing stars . Before entering the planetary region (epoch 1950), C/2011 J2 had an orbital period of several million years.[4] ejection trajectory .[4]
