Meanings of minor planet names

From Wikipedia, the free encyclopedia

This is a list of minor planets which have been officially named by the Minor Planet Center (MPC). The list consists of partial pages, each covering a number range of 1000 bodies citing the source after each minor planet was named for. An overview of all existing partial pages is given in section § Index.

Among the hundreds of thousands numbered minor planets only a small fraction have received a name so far. As of 2018, there are more than 21,000 named minor planets out of a total of half a million numbered ones (also see List of minor planets § Main index as numbers increase constantly).[1] Most of these bodies are named for people, in particular astronomers, as well as figures from mythology and fiction. Many minor planets are also named after places such cities, towns and villages, mountains and volcanoes; after rivers, observatories, as well as organizations, clubs and astronomical societies. Some are named after animals and plants. A few minor planets are named after exotic entities such as supercomputers or have an unknown origin (see Category:Minor planets with names of unknown origin).

The first few thousand minor planets have all been named, with the Jupiter trojan (3708) 1974 FV1 currently being the lowest-numbered unnamed minor planet.[2] The first 3 pages in the below table contain 1,000 named entries each. The first 13 and 33 pages contain at least 500 and 100 named entries each, respectively. The first range to contain no entries is 122001–123000. There are also several name conflicts with other astronomical objects, mostly with planetary satellites and among themselves.

Following a proposal of the discovering astronomer, new minor planet names are published in MPC's Minor Planet Circulars on a monthly basis. The MPC applies a set of rules for naming minor planets. These range from syntax restrictions to non-offensive meanings. Over the years the rules have changed several times. In the beginning, for example, most minor planets were named after female characters from Greek and Roman mythology.

You're watching FreeSchool! Thousands of years ago, ancient astronomers looked up at the sky and realized that some of the things they thought were stars were moving in ways they didn't expect. They called these errant objects planets, a word that means wandering stars. Five of these objects - Mercury, Venus, Mars, Jupiter, and Saturn - were identified and named in ancient times. Through the centuries, the tools astronomers used to study the skies became better and stronger, and three more planets were identified: Uranus, Neptune, and Pluto. However, as astronomers continued to study the outer reaches of our Solar System, they came to a startling realization: Pluto wasn't alone in the space beyond Neptune. As more and more objects were discovered near Pluto that were close to Pluto in size, astronomers realized that they couldn't ALL be planets. Something had to be done. In 2006 the International Astronomical Union created a new category: dwarf planets. For an object to qualify as a dwarf planet, it only had to meet two criteria: One, it must orbit around the Sun. Two, it must be massive enough for its own gravity to pull it into a spherical - or mostly spherical - shape. Planets had a third qualification they had to meet; they must have cleared their orbits of other objects. Since dwarf planets often share their orbits with asteroids, comets, debris, and even other dwarf planets, this third point made it easier to tell the difference between a planet and a dwarf planet. There are currently five officially recognized dwarf planets in the Solar System: Ceres, Pluto, Eris, Haumea, and Makemake. Of those five Ceres was discovered first, in 1801. That's because Ceres is located in the asteroid belt between Mars and Jupiter, making it easier to observe using the telescopes of the time and the only dwarf planet in the inner solar system. When it was discovered, Ceres was heralded as the fifth planet from the sun, and Jupiter was pushed to the sixth position. This new order only lasted a year before another new planet was observed near Ceres - then another, then another! Within a few decades, dozens of new objects had been discovered between Mars and Jupiter. By the 1850s, astronomers decided enough was enough, and reclassified all of the objects in the asteroid belt - including Ceres - as minor planets. Following the IAU's decision in 2006, Ceres was reclassified again as a dwarf planet. It is the largest object in the asteroid belt, and contains 25% of the asteroid belt's mass. It completes one rotation every 9 hours and one orbit around the sun every 4.6 years. Ceres has no moons or rings, but it does have a very thin atmosphere which contains traces of water vapor. It is the smallest of the recognized dwarf planets with a diameter of 590 miles or 950 kilometers. Ceres became the first of the dwarf planets to be visited by a spacecraft when the Dawn space probe entered its orbit on March 6, 2015. Pluto is the largest and most well-known dwarf planet. It was regarded as the ninth planet from its discovery in 1930 until its reclassification in 2006. Pluto is small and made of rocky ice, and it rotates slowly with a day that is 6.4 Earth days long. Because it is usually farther from the sun than Neptune, it takes 248 years for it to complete a single orbit around the sun. Pluto has a thin atmosphere made of nitrogen, methane, and carbon monoxide. Like Ceres, Pluto has no rings. Unlike Ceres, Pluto has five moons including Charon, which is so large that Pluto and Charon are sometimes called binary or double dwarf planets. Pluto was visited by the New Horizons spacecraft in July of 2015, capturing stunning images of the former planet and raising new questions about the composition and structure of this cold and distant world. Eris was named for the Greek goddess of discord and strife, which is fitting since the discovery of Eris is what prompted arguments about Pluto's status as a planet. When it was discovered in 2005, NASA initially called Eris the tenth planet, but discoveries of multiple other large objects in the area caused them to reconsider. Eris is slightly smaller than Pluto, but it is estimated to be more massive and it is believed to be covered with methane ice. It has one known moon, Dysnomia. Eris and its moon are two of the most distant known objects in the solar system, traveling much farther from the sun than Pluto does. It is estimated that Eris will take 558 years to complete one orbit around the sun. The discovery of another dwarf planet, Haumea, was announced in 2005. Unlike the rest of the dwarf planets, Haumea is oblong instead of shaped like a ball! Haumea appears to have water ice on its surface, and it is one of the fastest-spinning large objects in the solar system, completing a turn once every four hours. Its orbit is only a little longer than Pluto's, taking 284 years to travel once around the sun. Haumea, named for the Hawaiian goddess of fertility and childbirth, has two known moons. The moons, Hi'aka and Namaka, are named for two of the goddess' daughters. The fifth and final dwarf planet currently recognized is Makemake. Makemake was also discovered in 2005 and was named for the creator god in the mythology of the Rapa Nui people of Easter Island. Like the other dwarf planets of the Kuiper Belt, Makemake is covered in ices - made of methane, ethane, and possibly nitrogen ice. Although its diameter is only about two-thirds of Pluto's, Makemake's icy surface makes it the second-brightest object in the Kuiper Belt, after Pluto. In 2016 it was discovered that Makemake has at least one moon, which is as-yet unnamed. Astronomers believe that there are hundreds of objects in the solar system that are likely to be dwarf planets. As scientists continue to study them, it is likely that more and more will be added to our list. Until then, I hope you enjoyed learning about Ceres, Pluto, Eris, Haumea, and Makemake - the dwarf planets of the solar system. Goodbye till next time!
