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 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. [ 87 ]
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 ...
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 ...
The symbol for Ceres, as well as the second symbol for Uranus, was taken from material published by James L. Hilton. [104] The other dwarf-planet symbols were invented by Denis Moskowitz, a software engineer in Massachusetts. His symbols for Haumea, Makemake, and Eris appear in a NASA JPL infographic, as does the second symbol for Pluto. [105]
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 ...
Ceres is rich with water, the Dawn spacecraft finds. 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.
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.
