Iau planet names

What makes a planet a planet IAU? 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. When a body is initially sighted it is given a provisional name, which is later superseded by a permanent numerical designation once its orbit has been well determined.

There are several stages before a proposed name is accepted: 1. The discovery team suggests a suitable name to the two relevant IAU group.

See full list on iau. With the agreement of the WGPSN, the CSBN will assume responsibility for the naming of satellites of minor planets. 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 WGPSN is responsible for naming of satellites of planets. 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. Gallic, Inuit and Nors. The assignment of a particular name to a particular minor planet is the end of a long process that can take many decades: 1. It begins with the discovery of a Minor Planet that cannot be identified with any already-known object.

Such Minor Planets are given a provisional designation.

When a Minor Planet receives a permanent number, the discoverer of the Min. 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. A comet’s tail is formed when the Sun’s heat warms the coma or nucleus, which releases vapours into space. 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. Today, the IAU’s Division F Working Group on Small Body Nomenclature (SBN) is the responsible body for strategic matters related to comet naming. When a comet is discovered and confirme the Central Bureau for Astronomical Telegrams (CBAT) announces it on behalf of the IAU. It is then given a designation according to.

The scientific nomenclature for the designations of exoplanets usually consists of two elements: 1) a proper noun or abbreviation, sometimes with associated numbers 2) followed by a lowercase letter. The first element can derive from a number of sources. Alternatively, exoplanets are often named after the scientific instrument or project that discovered the exoplanet. Pegasi b, for instance, is an exoplanet around the star Pegasi in the constellation Pegasus. A handful of Gliese exoplanets also exist as well.

An example world with this naming is GJ 121. In particular proposed names should be: 1. Not too similar to an existing name of an astronomical object.

Names of individuals, places or events principally known for political, military or religio. In addition it is not allowed to propose: 1. Note: These names are modified based on the original proposals, to be consistent with the IAU rules. Note 1: The original name propose Veritas, is that of an asteroid important for the study of the solar system. Note 3: Note the typographical difference between AEgir and Aegir, the Norwegian transliteration.

Note 4: Ogmios is a name already attributed to an asteroid. Note 6: The original spelling of Lippershey was corrected to Lipperhey on 15. The name Althaea is also attributed to an asteroid. As the IAU had hope some of the names are derived from indigenous.

International Astronomical Union ( IAU ) Working Group for Planetary System Nomenclature (WGPSN). Planet and Satellite Names , Discoverers, and Themes. With the advent of the increased light-gathering abilities of the telescope, many more stars became visible,. The sky was divided into constellations by.

It operates under Division C – Education, Outreach and Heritage. An IAU process will be established to assign borderline objects into either dwarf planet and other categories. These currently include most of the Solar System asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies.

The IAU Working Group for Planetary System Nomenclature has approved the name Berry for a crater on Mercury. For more information, please see the Mercury map H-in the Gazetteer of Planetary Nomenclature. The NameExoWorlds campaign has selected planetary systems for naming composed of planets orbiting stars that could be observed with a small telescope in the latitude of the capital of each country. In many cases, the system has a link with the assigned country, such as the facilities used and the scientists involved in the discovery of the planet. HAT-P-36b is the only known planet in its star system, so far.

A public vote followe and by the time the polling closed on October 31st stellaphiles from 1countries had cast 572votes on exoplanet names. IAU Rules and Conventions Rules Names adopted by the IAU must follow various rules and conventions established and amended through the years by the Union. These include: Nomenclature is a tool and the first consideration should be to make it simple, clear, and unambiguous.

Ceres, a round object in the Asteroid Belt.
