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.
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 .
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 ...
Giuseppe Piazzi, discoverer of Ceres, the largest object in the asteroid belt: Ceres was known as a planet, but later reclassified as an asteroid and from 2006 as a dwarf planet. On January 1, 1801, Giuseppe Piazzi , chairman of astronomy at the University of Palermo , Sicily, found a tiny moving object in an orbit with exactly the radius ...
The dwarf planet Ceres, as imaged by NASA's Dawn spacecraft. As of 2024, only two missions have targeted and explored dwarf planets up close. On March 6, 2015, the Dawn spacecraft entered orbit around Ceres, becoming the first spacecraft to visit a dwarf planet. [85] On July 14, 2015, the New Horizons space probe flew by Pluto and its five moons.
Craters. 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).
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 ...
The resulting values can be divided by 10 to convert them into astronomical units (AU), resulting in the expression: a = 0.4 + 0.3 × 2 n . {\displaystyle a=0.4+0.3\times 2^{n}~.} For the far outer planets, beyond Saturn , each planet is predicted to be roughly twice as far from the Sun as the previous object.
