12P/Pons–Brooks is a periodic comet with an orbital period of 71 years. It fits the classical definition of a Halley-type comet with (20 years < period < 200 years). The next perihelion passage is 21 April 2024, with closest approach to Earth being 1.54 AU (230 million km) on 2 June 2024. The comet nucleus is estimated to be around 30 km in diameter assuming it was not producing too much dust and gas during the 2020 photometry. 12P/Pons–Brooks may be the parent body of the December κ-Draconids meteor shower.
