122P / de Vico ( 1846 D1 ) is a short-period comet with an orbital period of 74 years. It is an example of a comet such as Halley's comet with a period of 20 to 200 years. [5] The comet was discovered by Francesco de Vico in Rome on February 20, 1846.

On December 3, 2153, the comet will pass at a distance of about 0.694 AU from Uranus. [6]
In 1884, Daniel Kirkwood noted that this comet has similar elements to the 12P / Pons-Brooks comet. He suggested that the 122P / de Vico separated from the 12P / Pons - Brooks several centuries before the observation. Kirkwood later discovered that comets underwent a common perihelion in 991 AD.
