SOLAR SYSTEM

Detailed explanation-1: -Ceres has the shape of a flattened sphere with an equatorial radius of 490 km and a polar radius of 455 km, equivalent in volume to a sphere with a diameter of 940 km-i.e., about 27 percent that of Earth’s Moon. Although Ceres is the largest asteroid, it is not the brightest.

Detailed explanation-2: -In recognition of its planet-like qualities, Ceres was designated a dwarf planet in 2006 along with Pluto and Eris. NASA’s Hubble Space Telescope observations in 2003 and 2004 of Ceres as it rotated demonstrated that is a nearly spherical body. Ceres is approximately 585 miles (940 kilometers) across.

Detailed explanation-3: -It is only 590 miles (950 km) in diameter and has a mass of just 0.015 percent that of Earth. In fact, Ceres is so small that it is classified as both a dwarf planet and an asteroid, and is often named in scientific literature as one of the largest asteroids in the solar system.

Detailed explanation-4: -Round means that the force of gravity has overcome the strength of the materials that make up Ceres, squishing it together and forcing its surface to be approximately flat, according to the local force of gravity; over time, that makes a world round, not quite spherical, but bulging slightly at the equator.

Detailed explanation-5: -Dwarf planet Ceres is the largest object in the asteroid belt between Mars and Jupiter, and it’s the only dwarf planet located in the inner solar system. It was the first member of the asteroid belt to be discovered when Giuseppe Piazzi spotted it in 1801.
