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.
Geology of Ceres. Dawn spacecraft view of Occator Crater on Ceres in enhanced color, this image was taken on 4 May 2015. [1] 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 asteroid belt is the smallest and innermost known circumstellar disc in the Solar System. Classes of small Solar System bodies in other regions are the near-Earth objects, the centaurs, the Kuiper belt objects, the scattered disc objects, the sednoids, and the Oort cloud objects. About 60% of the main belt mass is contained in the four ...
Bright spots on Ceres. Several bright surface features (also known as faculae) were discovered on the dwarf planet Ceres by the Dawn spacecraft in 2015. The brightest cluster of spots ("Spot 5") is located in an 80-kilometer (50 mi) crater called Occator. [1][2] The largest and brightest component of the cluster is in the center of the crater ...
Scientists have detected ice on the planet's surface, which could mean Ceres is hiding an ocean below its frozen crust. Dwarf planet Ceres may have a huge ocean that could support life Skip to ...
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).
e. The geology of solar terrestrial planets mainly deals with the geological aspects of the four terrestrial planets of the Solar System – Mercury, Venus, Earth, and Mars – and one terrestrial dwarf planet: Ceres. Earth is the only terrestrial planet known to have an active hydrosphere. Terrestrial planets are substantially different from ...
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] Like the planets, Ceres is differentiated: it has a crust, a mantle and a ...
