This compilation demonstrates, however, that the names of the planets and Moon have appeared in IAU resolutions or in wording of documents approved by IAU resolution approved by IAU General Assemblies multiple times, and continue to be in ubiquitous use. While Resolution B5 defined the category of dwarf planet, Resolution B6 explicitly lists Pluto as an example. One also sees these planet names are used ubiquitously by modern IAU working groups e. Planetary nomenclature, like terrestrial nomenclature, is used to uniquely identify a feature on the surface of a planet or satellite so that the feature can be easily located, described, and discussed.
The procedure is as follows:. Dwarf planets are planetary-mass objects orbiting the Sun that are massive enough to be rounded by their own gravity, but are not planets or satellites. Unlike planets, these bodies have not cleared the neighbourhood around their orbits, and their paths sometimes cross with other, often similar, objects. There are currently five identified dwarf planets in our Solar System, each named after a God from Greek, Polynesian, or Roman mythologies. In addition all of these but Ceres are also classified as plutoids, meaning that they are dwarf planets that orbit beyond Neptune and have an absolute magnitude H greater than 1.
The names of features on the bodies in the Pluto system are related to mythology and the literature and history of exploration:. Modern technology has made it possible to discover satellites down to 1 km in size or even smaller.
The greatly increased discovery rate of satellites has made it necessary to extend the existing name categories for the satellites of Jupiter and Saturn whose names are drawn from the Greco-Roman mythology. The satellites of Saturn have so far been named for the Greco-Roman Titans, descendants of the Titans, Giants and the Roman god of the beginning. In order to internationalize the names, we now also allow names of giants and monsters in other mythologies so far Gallic, Inuit and Norse.
The assignment of a particular name to a particular minor planet is the end of a long process that can take many decades:. The names of individuals or events principally known for political or military activities are unsuitable until years after the death of the individual or the occurrence of the event. There are more detailed guidelines for unusual Minor Planets in certain dynamical groups, for example:. Accepted names become official when they are published, along with their accompanying citations, in the Minor Planet Circulars, issued monthly by the Minor Planet Center.
The WGSBN recognizes the need to limit the numbers of Minor Planets named, and it requests individual discoverers and teams to propose no more than two names each two months.
Contrary to some recent media reports it is not possible to buy a name for a minor planet. If you have a name you would like to apply to a minor planet, the best advice is "Go out and discover one! The alphabetic list of all names is available at the Minor Planet Center including the discovery circumstances. A comet is a body made of rock and ice, typically a few kilometres in diameter, which orbits the Sun.
Comets may pass by the Sun only once or go through the Solar System periodically. During the 19th century, comets were only given names after their second apparition, while those that had only appeared once were designated by a combination of year of discovery, numbers both Arabic and Roman and letters.
Sometimes, the name of the discoverer was referred to in parentheses. It was not until the 20th century that comets were routinely named after their discoverers. It is then given a designation according to the following pattern see Resolution C. The precise method, including exceptions and special cases, is described in the Cometary Designation System IAU resolution. To complete the designation, comets are either given the name of the discovery team or of one or two individual members of the team last name for an individual or one word or acronym for a team of astronomers.
Discoveries by individuals are named for up to three independent discoverers. The names appear in chronological order and separated by a hyphen.
In very rare cases the title can consist of three discoverers, or can even be generic. More detailed guidelines explaining the process of assigning the names of the discoverers to a comet can be found in this IAU document. Also read this essay on the web pages of the International Comet Quarterly. See the dedicated page " Naming Stars ".
The designation of astronomical objects beyond the Solar System should consist of at least two parts — a leading acronym and a sequence value. More information : Complete specifications concerning designations for astronomical radiation sources outside the solar system are published by the Working Group on Astronomical Designations in IAU Commission B2.

For those who are unfamiliar the IAU is the official group that oversees new discoveries in space, including planets, stars, comets and other objects.
First of all, the name you give your planet in your story will depend on the type of planet it is. We will explain each type of planet below. Before we explain these planet types, here are some general rules to follow:. These are the big planet names that you are likely to already know. Name the planet after a Greek or Roman god. For example:. Okay, so you get the picture — Major planets are named after mythological gods and goddesses. Do some research and find a list of gods in Roman and Greek myths — Use this list to help you create a major planet name.
Dwarf planets are planet-like objects in the solar system — But they are technically not planets. The most common dwarf planet is Pluto. Again the names of dwarf planets can come from Roman or Greek myths.
Here are some examples coming from Greek Mythology:.
