Ceres' classification has been changed many times, and it was all the result of disagreement among astronomers. John Boder believed that Ceres was the "missing planet" between Mars and Jupiter, hundreds of millions of kilometers from the Sun. Ceres was given the symbol of a planet, and before more asteroids were discovered, Ceres (along with Homo sapiens, Marriage and Vesta) was listed as a planet in astronomy for nearly half a century.
However, when other objects were discovered in the same range, it was slowly understood that Ceres was just one of many similar types of objects. William Herschel coined the term asteroid (a star-like object) in 1802 to refer to this object, writing that "it is so indistinguishable from the stars that the best telescopes would think it is a small star". As the first asteroid to be discovered, it is listed as the asteroid No. 1 Ceres under the modern asteroid numbering system.
In 2006, the debate over whether Pluto is a "planet" raised the question of whether Ceres should also be reclassified as a planet. Prior to the official definition of a planet by the International Astronomical Union, a planet was defined as "a celestial body that: (a) is sufficient mass to overcome rigid force by its own gravity and therefore can take on a hydrostatically equilibratory shape (close to a sphere); (b) orbiting a star and not a planet or a satellite of a planet".
According to this definition, Ceres would be the fifth planet in order from the inner side of the solar system. However, this definition was not accepted, and a new definition entered into force on 24 August 2006: "A planet that meets (a) and (b) and must be cleared of objects in adjacent orbits".
By this definition, Ceres is not a planet (because its orbit in the asteroid belt is filled with thousands of asteroids) and is classified as a "dwarf planet" (along with Pluto and Eris), but it is not clear whether it is still an asteroid. In astronomy, there are also objects with dual identities such as asteroid belt comets, so it is not excluded that a dwarf planet can have other names.
Ceres is by far the largest object in the asteroid belt, but with the discovery of the Kriber's Belt and its celestial bodies, objects larger than Ceres have also been discovered, including the asteroids (28978) (Ixion), (50,000 Quaoar), asteroids (Orcus), and 2003 UB313 (Eris), while the newly discovered farthest object (90377), Sedna, may also be larger than Ceres, which may have come from the inner layers of the Ultracloud clouds. Pluto is also sometimes thought of as a Kaiburg Belt object.

It is the only dwarf planet located in the main belt. Discovered by the Italian Piazzi on January 1, 1801. Its average diameter is 952 km.
Ceres orbits the Sun once an Earth year. Ceres' infrared spectrum shows the ubiquity of hydrated minerals, which shows the presence of large amounts of water inside it.

Ceres was discovered by the Italian Piazzi on January 1, 1801. With an average diameter of 952 kilometers, it is the largest and heaviest object in the asteroid belt of the solar system. Ceres orbits the Sun once an Earth year.
The Earth's solar system is home to four terrestrial planets: Mercury, Venus, Earth, and Mars, and a terrestrial dwarf planet, Ceres.
Dwarf planets, or "dwarf planets", are between planets and asteroids, orbit the Sun, are massive enough to overcome solid gravity to achieve a hydrostatic equilibrium (nearly spherical) shape, do not empty other objects in their orbits, and are not satellites.
The terrestrial planets are all structurally similar: they are a core dominated by iron and mostly metal, surrounded by a silica-dominated mantle. Terrestrial planets have canyons, impact craters, mountains, and volcanoes.
The atmospheres of terrestrial planets are all regenerative atmospheres, unlike Jupiters, which come directly from the native atmosphere of the solar nebula.

Republic of Ireland), located in the west of Europe, west of the Atlantic Ocean, east of the Irish Sea, and the United Kingdom across the sea, is an important passage from North America to Europe. Ireland has a beautiful natural environment, meadows, green trees, and rivers, and is known as the "Emerald Isle Country". The domestic climate is mild and humid, the temperature is relatively balanced in various places, and the summer is sunny. >>>More
