Systematic name

A systematic name is a name given in a systematic way to one unique group, organism, object or chemical substance, out of a specific population or collection. Systematic names are usually part of a nomenclature.

A semisystematic name or semitrivial name is a name that has at least one systematic part and at least one trivial part.

Creating systematic names can be as simple as assigning a prefix or a number to each object (in which case they are a type of numbering scheme), or as complex as encoding the complete structure of the object in the name. Many systems combine some information about the named object with an extra sequence number to make it into a unique identifier.

Systematic names often co-exist with earlier common names assigned before the creation of any systematic naming system. For example, many common chemicals are still referred to by their common or trivial names, even by chemists.

In chemistry

In chemistry, a systematic name describes the chemical structure of a substance, thus giving some information about its chemical properties.

Comet Holmes

Comet Holmes (official designation: 17P/Holmes) is a periodic comet in the Solar System, discovered by the British amateur astronomer Edwin Holmes on November 6, 1892. Although normally a very faint object, Holmes became notable during its October 2007 return when it temporarily brightened by a factor of about half a million, in what was the largest known outburst by a comet, and became visible to the naked eye. It also briefly became the largest object in the Solar System, as its coma (the thin dissipating dust ball around the comet) expanded to a diameter greater than that of the Sun (although its mass remained minuscule).

Discovery

Comet Holmes was discovered by Edwin Holmes on November 6, 1892, while he was conducting regular observations of the Andromeda Galaxy (M31). Its discovery in 1892 was possible because of an increase in its magnitude similar to the 2007 outburst; it brightened to an approximate magnitude of 4 or 5 before fading from visibility over a period of several weeks.

Holmes (surname)

Holmes is an English-language surname with several origins.

The name can be a variant of the surname Holme. This surname has several etymological origins: it can be derived from a name for someone who lived next to a holly tree, from the Middle English holm; it can also be derived from the Old English holm and Old Norse holmr. Another origin of Holmes is from a placename near Dundonald, or else a place located in the barony of Inchestuir. The surname is also sometimes an Anglicised form of the Gaelic Mac Thomáis; similarly, Holmes can also be a variant of Cavish, derived as an Anglicised form of Mac Thámhais.
