Posted on the 01 April 2011 by Gabe12logan
Ceres is the smallest dwarf planet of solar system discovered in 1801 and even half a century had the status of the planet. Named after the Roman goddess Ceres. Ceres is the largest body of the asteroid belt located between Mars and Jupiter.
With a diameter of about 950 km, Ceres is by far the largest and most massive body in the asteroid belt, and contains one-third (32%) of the total mass of the belt. Recent observations have revealed that Ceres is spheroidal, unlike the irregular shapes of smaller bodies with lower gravity. Ceres area is likely to consist of a mixture of ice, water and various hydrated minerals like carbonates and clays. Ceres apparent magnitude is ranging from 6.7 to 9.3 and therefore are underexposed to be seen with the naked eye.

There are indications that the surface of Ceres is warm enough to support a weak atmosphere and that on the surface can be found frosting.
