The Delta Cancrids is a medium strength meteor shower lasting from December 14 to February 14,[1] the main shower from January 1 to January 24.[2][3] The radiant is located in the constellation of Cancer, near Delta Cancri. It peaks on January 17 each year, with only four meteors per hour.[2][3] It was first discovered in 1872, but the first solid evidence of this phenomenon came in 1971.[1] The source of this meteor shower is unknown, it has been suggested that it is similar to the orbit of asteroid 2001 YB5.[4]
