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 .
Ceres is saturated with impact craters.Many have a central pit or bright spot. In the first batch of 17 names approved by the IAU, craters north of 20° north latitude had names beginning with A–G (with Asari being the furthest north), those between 20° north and south latitude beginning with H–R, and those further south beginning with S–Z (with Zadeni being the furthest south).
The geology of Ceres is the scientific study of the surface, crust, and interior of the dwarf planet Ceres. It seeks to understand and describe Ceres' composition, landforms, evolution, and physical properties and processes. The study draws on fields such as geophysics, remote sensing, geochemistry, geodesy, and cartography (see Planetary geology).
Examples are Ceres in the asteroid belt and Pluto in the Kuiper belt. [46] Dynamicists usually prefer using gravitational dominance as the threshold for planethood, because from their perspective smaller bodies are better grouped with their neighbours, e.g. Ceres as simply a large asteroid and Pluto as a large Kuiper belt object.
The Phocaea family orbit between 2.25 and 2.5 AU from the Sun. [102] Skirting the outer edge of the asteroid belt is the Cybele group, orbiting between 3.3 and 3.5 AU. These have a 7:4 orbital resonance with Jupiter. The Hilda family orbit between 3.5 and 4.2 AU with relatively circular orbits and a stable 3:2 orbital resonance with Jupiter ...

The brightest cluster of spots ("Spot 5") is located in an 80-kilometer (50 mi) crater called Occator, [1] [2] which is located at 19.86° N latitude; 238.85 E longitude. [1] [2] Spots on Ceres from different angles. The spot in the center of the crater is named Cerealia Facula, [16] and the group of spots to the east - Vinalia Faculae. [17]
In ancient Roman religion, Ceres (/ ˈ s ɪər iː z / SEER-eez, [1] [2] Latin:) was a goddess of agriculture, grain crops, fertility and motherly relationships. [3] She was originally the central deity in Rome's so-called plebeian or Aventine Triad, then was paired with her daughter Proserpina in what Romans described as "the Greek rites of Ceres".
