Comet Pons–Brooks is a periodic comet with an orbital period of 71 years. Comets with an orbital period of 20–200 years are referred to as Halley-type comets. It is one of the brightest-known periodic comets, reaching an absolute visual magnitude of about 5 in its approach to perihelion. Comet Pons–Brooks was conclusively discovered at Marseilles Observatory in July 1812 by Jean-Louis Pons, and on its next appearance in 1883 by William Robert Brooks. However it has been confirmed 12P/Pons–Brooks was observed before the 19th century. The last perihelion passage was 21 April 2024, with closest approach to Earth being 1.55 AU (232 million km) on 2 June 2024. During the 2024 apparition the comet brightened to a magnitude of 3.8.
