Ceres was first considered as an asteroid. It was named and discovered by an Italian Astronomer – Giuseppe Piazzi in early 1801. The astronomers have planned to visit Ceres in 2015. NASA’s Dawn Spacecraft is planning and making its way to Ceres since September 2012. There is lots of expectation regarding this planet since Ceres remains as a possible target for human colonization. It has an abundance of minerals, water and ice. If the mission visits the planet, then Ceres will remain as the initial dwarf planet entered by the spacecraft. Ceres is the least massive and smallest planet among the dwarf planets. It has a mysterious white spot. You can see the spots in the recent photos and also in some of the old Hubble photographs.
The pictures were taken by the Dawn spacecraft during their approach. It is said that Ceres loses about six kilograms of mass in the steam. The Herschel Space telescope has observed impressive amounts of water vapour shooting from the Ceres surface. It is said that it was the first time to see water vapour, especially in the asteroid belt. The scientists think that it should be caused due to the warming of icy surfaces in the Ceres. They have discovered fourteen similar objects by the year 1851. They did not take a lengthy time to discover, and thus, it came to be referred as minor planets. After Pluto, Ceres also came under the dwarf planet category in the year 2006. Ceres was often referred as a planet especially in the first fifty years of its discovery.
