Comet LINEAR, formal designation C/2012 L2, is a faint non-periodic comet that had a distant perihelion on May 2013. Preliminary calculations of its orbit by Maik Meyer noted a striking similarity with that of C/1785 A1 (Messier–Mechain), however it is purely a coincidence rather than the return of the latter comet.
Discovery and observations
The comet was discovered as a 19.4-magnitude object from photographs taken by the Lincoln Near-Earth Asteroid Research survey on the morning of 1 June 2012. Five days after discovery, Maik Meyer noted that the preliminary orbit of this comet was initially similar to that of C/1785 A1, however later concluded these comets were unrelated from one another. Its aphelion distance suggested it may have been a dynamically new object that originated from the inner regions of the Oort cloud, therefore imaging polarimetry of the comet was conducted to further study the composition of these objects.
