ABSTRACT
A short-period comet discovered independently in 1900 by Michel Giacobini and in 1913 by Ernst Zinner. With a period of 6.61 years it is, like the majority of short-period comets, a member of Jupiter's comet family. It reached its greatest magnitude of 7 when it made its closest approach to Earth in 1946, passing at a distance of 0.26 AU
