273P/Pons–Gambart, also called Comet Pons-Gambart, is a short-period comet first discovered on June 21, 1827 by Jean-Louis Pons and Jean-Félix Adolphe Gambart. It has a 186 year orbit. It fits the classical definition of a Halley-type comet with (20 years < period < 200 years). 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 pre-recovery short-arc orbital calculations for Pons-Gambart were completely wrong because the comet only had a 1-month observation arc with poor data.[4]

The original name when first discovered was C/1827 M1.[5] Before the 2012 return, when Comet Pons–Gambart was speculated to have a roughly 60 year orbit it was suspected of possibly being comet 1110 K1.[1]
Of the numbered periodic comets only 153P/Ikeya-Zhang has a longer orbital period.

Комета По́нса — Гамба́ра (P/1827 M1) — короткопериодическая комета, открытая 21 июня 1827 года французскими астрономами Ж.-Л. Понсом и А. Гамбаром в созвездии Кассиопеи. Максимальная яркость оценивалась в 5-6m. 24 и 25 июня комета наблюдалась Понсом в нижней кульминации с меридианным инструментом. В июле наблюдалась Ж. Вальцем в Ниме. Последнее наблюдение кометы состоялось 21 июля. Указаний на хвост не было.Другой контент может иметь иную лицензию.
