Comet Bennett, formally known as C/1969 Y1 (old style 1970 II and 1969i), was one of two brilliant comets to grace the 1970s, along with Comet West. The name is also borne by an altogether different comet, C/1974 V2.
Discovered by John Caister Bennett on December 28, 1969 while still almost two AUs from the Sun, it reached perihelion on March 20, passing closest to Earth on March 26, 1970 as it receded, peaking at magnitude 0.[1] It was last observed on February 27, 1971.[1]
