Dwarf planet Ceres is the largest object in the asteroid belt between Mars and Jupiter and the only dwarf planet located in the inner solar system. It was the first member of the asteroid belt to be discovered when Giuseppe Piazzi spotted it in 1801. And when Dawn arrived in 2015, it became the first dwarf planet to receive a visit from a spacecraft. Called an asteroid for many years, Ceres is so much bigger and so different from its rocky neighbors that scientists classified it as a dwarf planet in 2006. Even though Ceres comprises 25 percent of the asteroid belt's total mass, tiny Pluto is still 14 times more massive. If you wanted to compare it to the Earth, think of it like this. If the Earth was a nickel, Ceres would be a poppy seed in comparison. 9. The History And Discovery Of Ceres The finding of Ceres is a bit more in depth than we teased in the last entry, so here's a bit of a deeper look at its finding. Johann Elert Bode first suggested that an undiscovered planet could exist between the orbits of Mars and Jupiter in 1772. Kepler had already noticed the gap between Mars and Jupiter in 1596. Bode observed that there was a regular pattern in the size of the orbits of known planets, and that the pattern was marred only by the large gap between Mars and Jupiter. A curious finding indeed. The pattern predicted that the missing planet ought to have an orbit with a radius near 2.8 astronomical units (AU). William Herschel's discovery of Uranus in 1781 near the predicted distance for the next body beyond Saturn increased faith the beliefs of Bode, and in 1800, a group headed by Franz Xaver von Zach, editor of the Monatliche Correspondenz, sent requests to twenty-four experienced astronomers (whom he dubbed the "celestial police"), asking that they combine their efforts and begin a methodical search for the expected planet. Although they did not discover Ceres, they later found several large asteroids. But this wasn't the end, this was just the beginning. One of the astronomers selected for the search was Giuseppe Piazzi, a Catholic priest at the Academy of Palermo, Sicily. Before receiving his invitation to join the group, Piazzi discovered Ceres in January 1801. Though he didn't know it at the time. Rather, he thought it was a comet, and apparently found Ceres 24 times! Eventually, he sent his finding to his colleagues, and by the end of 1801 they had tracked down Ceres and was able to further document its movements. But was it a Dwarf Planet right then and there? Nope! 8. Classification Issues Something you must remember is that when it came to early astronomy is that the universe as a whole was still unknown in the grand scale and various notions about were changing and evolving with each century and new discovery. The categorization of Ceres has changed more than once and has been the subject of some disagreement over the years and decades since its finding. Johann Elert Bode believed Ceres to be the "missing planet" he had proposed to exist between Mars and Jupiter, at a distance of 419 million km (2.8 AU) from the Sun. Ceres was assigned a planetary symbol, and remained listed as a planet in astronomy books and tables (along with 2 Pallas, 3 Juno, and 4 Vesta) for half a century. As other objects were discovered in the neighborhood of Ceres, it was realized that Ceres represented the first of a new class of objects. In 1802, with the discovery of 2 Pallas, William Herschel coined the term asteroid ("star-like") for these bodies, writing that "they resemble small stars so much as hardly to be distinguished from them, even by very good telescopes". As the first such body to be discovered, Ceres was given the designation 1 Ceres under the modern system of minor-planet designations. By the 1860s, the existence of a fundamental difference between asteroids such as Ceres and the major planets was widely accepted, though a precise definition of "planet" was never formulated. At the time, anyway. So what changed? Pluto, that's what. If you recall, for a long time, Pluto was the 9th planet of the solar system (and still is in the minds of many). But in 2006, a massive debate waged between scientists and astronomers as to whether Pluto WAS a planet, or something else. This of course brought up Ceres, who at one time was considered a planet before the change to asteroid classification. #InsaneCuriosity #Ceres #TheSolarSystem
