The surface of Ceres is a mixture of materials. Water ice is present on the surface, along with darker organic material and regolith. Dark materials cover much of Ceres’ exterior. Phyllosilicates and ammonium are found in the ice mantle.

Ceres follows a two-layer model. The rocky core has a radius of 170 kilometers. An ice mantle up to 100 kilometers thick surrounds this core. Clathrate hydrates exist in the subsurface layers of Ceres.

Ceres is geologically active, with evidence of recent water activity. Salty water exists below the surface. The dwarf planet has a mass of 9.44 x 10^23 kilograms and a diameter of about 946 kilometers. Ceres makes up about 1/3 of the total mass of the asteroid belt.

The water content of Ceres is estimated to be 25% of its mass. The surface temperature varies between -38°C in sunlit areas and -143°C in shadowed regions. Ceres has a very thin and transient atmosphere.

What is the atmosphere of Ceres?

Ceres possesses an extremely thin atmosphere primarily composed of water vapor. Dawn spacecraft detected this tenuous layer during its 2015-2016 orbit. Surface pressure measures 10^-3 to 10^-4 times Earth’s atmosphere. Solar radiation causes ice particles to sublimate, replenishing the transient atmosphere. Weak gravity (2.8% of Earth’s) makes atmosphere retention difficult. Other gases like carbon dioxide potentially exist.

The atmosphere of Ceres could be nitrogen-rich, containing up to 40% nitrogen. A’Hearn & Feldman (1992) researched the water vapor content in Ceres’ atmosphere. Solar radiation easily breaks down the ice molecules on Ceres’ surface, releasing water vapor and other gases into the atmosphere. The Herschel Space Observatory confirmed the presence of water vapor in Ceres’ atmosphere in 2012. Ceres’ atmosphere contains small amounts of methane and ammonia.

Ceres has ice volcanoes composed of ice instead of rock. Sori et al. (2017) studied these cryovolcanoes, which erupt with frozen materials and contribute to the atmosphere. Ice sublimating from the surface is another significant source of Ceres’ atmosphere. De Sanctis et al. (2015) found that Ceres’ surface consists of 25% water ice, providing ample material for sublimation. The Dawn spacecraft, which studied Ceres in detail starting in 2015, revealed the complex and dynamic geology of the dwarf planet, including cryovolcanic flows on its surface.
