Naming of comets
Comets have been observed for over 2,000 years. During that time, several different systems have been used to assign names to each comet. As a result, many comets have more than one name.
The simplest system names comets after the year in which they were observed (e.g. the Great Comet of 1680). Later a convention arose of naming comets after the people who discovered them (e.g. Comet Hale–Bopp) or performed the first detailed study of that comet (e.g. Halley's Comet).
During the twentieth century, improvements in technology and dedicated searches led to a massive increase in the number of comet discoveries, which was accommodated by introducing a numeric designation scheme. The original scheme assigned a code that depended on the order comets were observed to pass through perihelion (e.g. Comet 1970 II). Continued increases in the numbers of comet discoveries made this scheme impractical, so a new system was adopted in 1994 and remains in operation. The current system assigns a code based on the type of orbit and the date of discovery (e.g. C/2012 S1).
Before any systematic naming convention was adopted, comets were named in a variety of ways. Prior to the early 20th century, most comets were simply referred to by the year when they appeared e.g. the "Comet of 1702".
Particularly bright comets which came to public attention (i.e. beyond the astronomy community) would be described as the great comet of that year, such as the "Great Comet of 1680" and "Great Comet of 1882". If more than one great comet appeared in a single year, the month would be used for disambiguation e.g. the "Great January comet of 1910". Occasionally other additional adjectives might be used.
Possibly the earliest comet to be named after a person was Caesar's Comet in 44 BC, which was so named because it was observed shortly after the assassination of Julius Caesar and was interpreted as a sign of his deification. Later eponymous comets were named after the astronomer(s) who conducted detailed investigations on them, or later those who discovered the comet.
After Edmond Halley demonstrated that the comets of 1531, 1607, and 1682 were the same body and successfully predicted its return in 1759, that comet became known as Halley's Comet. Similarly, the second and third known periodic comets, Encke's Comet and Biela's Comet, were named after the astronomers who calculated their orbits rather than their original discoverers. Later, periodic comets were usually named after their discoverers, but comets that had appeared only once continued to be referred to by the year of their apparition.
The first comet to be named after the person who discovered it, rather than the one who calculated its orbit, was Comet Faye – discovered by Hervé Faye in 1843. However, this convention did not become widespread until the early 20th century. It remains common today.
