Detection of coma activity of the ACO/quasi-HILDA object 212P/2000YN 30

Abstract

The quasi-Hilda object 212P/2000YN30, which has a cometary-like orbit, was found to display a dust tail structure between 2009 January and March. From orbital calculations, it is shown that this object could have been an active comet in the past before being transported to its current orbital configuration in quasi-stable 3:2 resonance with Jupiter. © 2013.
