Ceres has spectral similarities to C-type asteroids, [3] which are rich in volatiles and carbonaceous compounds. Ceres is also sometimes classified as a G-type asteroid, [12] [13] which is a subtype of the Tholen C-class and characterized by abundant phyllosilicates, such as clay minerals. Ceres is not associated with any asteroid family or ...
Dawn is a retired space probe that was launched by NASA in September 2007 with the mission of studying two of the three known protoplanets of the asteroid belt: Vesta and Ceres. [1] In the fulfillment of that mission—the ninth in NASA's Discovery Program — Dawn entered orbit around Vesta on July 16, 2011, and completed a 14-month survey ...
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 mountain was discovered on images taken by the Dawn spacecraft in orbit around Ceres in 2015. [6] It is estimated to have an average height of about 4 km (2.5 mi; 13,000 ft) and a maximum height of about 5 km (3.1 mi; 16,000 ft) on its steepest side; it is about 20 km (12 mi; 66,000 ft) wide at the base.
Nasa has issued an alert for a stadium-sized asteroid set to make a close approach to Earth on Tuesday.. The 2024 ON asteroid measures 290 metres (950 feet) across and will come within 1 million ...
Haulani / h aʊ ˈ l ɑː n i / is an impact crater located on the dwarf planet Ceres that contains "Spot 1", one of the bright spots observed by the Dawn spacecraft. The crater was named after Haulani, the Hawaiian goddess of plants.

Sometimes Ceres is classified as a G-type asteroid. The Cererian surface is relatively warm. The maximum temperature with the Sun overhead was estimated from measurements to be 235 K (about −38 °C, −36 °F) on 5 May 1991. Prior to the Dawn mission, only a few Cererian surface features had been unambiguously detected.
