C/1881 K1 (also called the Great Comet of 1881, Comet Tebbutt, 1881 III, 1881b) is a long-period comet discovered by John Tebbutt on May 22, 1881 at Windsor, New South Wales. It is called a great comet because of its brightness at its last apparition. The comet was observed in the southern hemisphere from its discovery to June 11; it then became visible in the night sky of the northern hemisphere by June 22 as a spectacular object to the naked eye. The comet was still visible to the naked eye in August but by the end of the month the tail was not discernible. In the Alps at an altitude between 1000 to 2000 meters, Camille Flammarion observed the comet until the beginning of September. The last successful telescope observation of the comet was on February 15, 1882. Long-period comets have highly eccentric orbits and periods ranging from 200 years to thousands of years.
