C/1490 Y1 is a comet that was recorded and observed across East Asia, particularly China and Korea, from December 1490 to February 1491. It is believed to be the parent body of the Quadrantids meteor shower.[citation needed]
John Russell Hind,[5] Benjamin Peirce, and Ichiro Hasegawa[6] made the initial orbital calculations for the comet, which all resulted in a parabolic trajectory around the Sun.[1]
