Ceres (minor-planet designation: 1 Ceres) is a dwarf planet in the middle main asteroid belt between the orbits of Mars and Jupiter. It was the first known asteroid , discovered on 1 January 1801 by Giuseppe Piazzi at Palermo Astronomical Observatory in Sicily , and announced as a new planet .
Occator / ɒ ˈ k eɪ t ər / is an impact crater located on Ceres, the largest object in the main asteroid belt that lies between the orbits of Mars and Jupiter, that contains "Spot 5", the brightest of the bright spots observed by the Dawn spacecraft. It was known as "Region A" in ground-based images taken by the W. M. Keck Observatory on ...
Oxo / ˈ ɒ ʃ oʊ / is a small impact crater on the dwarf planet Ceres. Located in Ceres's northern hemisphere, it is the second-brightest feature on Ceres, after Haulani Crater . The crater was named after the Candomblé (and Yoruba ) god of agriculture.
The mountain was discovered on images taken by the Dawn spacecraft in orbit around Ceres in 2015. [6] It is estimated to have an average height of about 4 km (2.5 mi; 13,000 ft) and a maximum height of about 5 km (3.1 mi; 16,000 ft) on its steepest side; it is about 20 km (12 mi; 66,000 ft) wide at the base.
10 Hygiea is a major asteroid located in the main asteroid belt.With a mean diameter of between 425 and 440 km and a mass estimated to be 3% of the total mass of the belt, [11] it is the fourth-largest asteroid in the Solar System by both volume and mass, and is the largest of the C-type asteroids (dark asteroids with a carbonaceous surface) in classifications that use G type for 1 Ceres.
The four largest asteroids constitute half the mass of the asteroid belt. Ceres is the only asteroid that appears to have a plastic shape under its own gravity and hence the only one that is a dwarf planet. [74] It has a much higher absolute magnitude than the other asteroids, of around 3.32, [75] and may possess a surface layer of ice. [76]
4608 Wodehouse, provisional designation 1988 BW 3, is a background asteroid and suspected trojan of Ceres from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 19 January 1988, by Belgian astronomer Henri Debehogne at ESO's La Silla Observatory in northern Chile.
Piazzi named it "Ceres Ferdinandea," after the Roman and Sicilian goddess of grain and King Ferdinand IV of Naples and Sicily. The Ferdinandea part was later dropped for political reasons. Ceres turned out to be the first, and largest, of the asteroids existing within the asteroid belt. Ceres is today called a dwarf planet.
