The Great January Comet of 1910, named after the date it appeared. 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".
The official names of non-periodic comets begin with a "C"; the names of periodic comets begin with "P" or a number followed by "P". Comets that have been lost or disappeared have names with a "D". Comets whose orbit has not been determined are designated with a "X" prefix.
A comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing.This produces an extended, gravitationally unbound atmosphere or coma surrounding the nucleus, and sometimes a tail of gas and dust gas blown out from the coma.
For example, Comet Bennett (1969i) became 1970 II. Increasing numbers of comet discoveries made this procedure difficult to operate, and in 2003 the IAU's Committee on Small Body Nomenclature approved a new naming system, [30] and in its 1994 General Assembly the IAU approved a new designation system that entered into force in 1995 January 1.

In comet nomenclature, the letter before the "/" is either "C" (a non-periodic comet), "P" (a periodic comet), "D" (a comet that has been lost or has disintegrated), "X" (a comet for which no reliable orbit could be calculated —usually historical comets), "I" for an interstellar object, or "A" for an object that was either mistakenly ...
The confirmation of the comet's return was the first time anything other than planets had been shown to orbit the Sun. [36] It was also one of the earliest successful tests of Newtonian physics, and a clear demonstration of its explanatory power. [37] The comet was first named in Halley's honour by French astronomer Nicolas-Louis de Lacaille in ...
