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 .
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.
For the giant planets, the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure. [ 11 ] Because Sedna and 2002 MS 4 have no known moons, directly determining their mass is impossible without sending a probe (estimated to be from 1.7x10 21 to 6.1×10 21 kg for Sedna [ 12 ] ).
By far the largest object within the belt is the dwarf planet Ceres. The total mass of the asteroid belt is significantly less than Pluto 's, and roughly twice that of Pluto's moon Charon . The asteroid belt is a torus -shaped region in the Solar System , centered on the Sun and roughly spanning the space between the orbits of the planets ...
The aphelion distance between the Earth's and Sun's centers is currently about 1.016 71 AU or 152,097,700 km ... Dwarf planet Ceres: 380,951,528 km (236,712,305 mi)
Ceres is the largest dwarf planet in the inner solar system, and new findings from the Dawn spacecraft reveal this body is covered in salty oceans. ... housing an ocean far deeper than any found ...
Ceres, the largest object in the asteroid belt between Mars and Jupiter, is an "ocean world" with a big reservoir of salty water under its frigid surface, scientists said in findings that raise ...
The geology of the dwarf planet, Ceres, was largely unknown until Dawn spacecraft explored it in early 2015. However, certain surface features such as "Piazzi", named after the dwarf planets' discoverer, had been resolved.[a] Ceres's oblateness is consistent with a differentiated body, a rocky core overlain with an icy mantle.
