Comet 12P/Pons-Brooks

This periodic comet (T = 71 years) was discovered in 1812. It will reach perihelion in April 2024, and pass 1.55 AU from Earth in June 2024. On 20 July 2023 it increased in brightness about 100 times, probably the result of an outburst that released a large amount of gas and dust. The asymmetrical outburst resulted in this peculiar horseshoe shape. A comet with horns!
