273P/Pons–Gambart
273P/Pons–Gambart, also called Comet Pons-Gambart, is a long-period comet first discovered on June 21, 1827 by Jean-Louis Pons and Jean-Félix Adolphe Gambart. It was lost and was not recovered until November 7, 2012, when amateur astronomer Rob Matson discovered a comet, and it was identified that the orbital calculations for Pons-Gambart were completely wrong.[2]
