The asteroid belt is the region of the Solar System located roughly between the orbits of the planets Mars and Jupiter.eres, the asteroid belt's only dwarf planet, is about 950 km in diameter, whereas Vesta, Pallas, and Hygiea have mean diameters of less than 600 km.
Most known asteroids are found in the Main Belt between Mars and Jupiter, or in the Kuiper Belt past the orbit of Neptune. But there are thousands that orbit at least as close to the Sun as Earth.The vast majority of asteroids are smaller than 1 kilometer in diameter. The largest asteroid in the Main Belt is Ceres, which has been designated a dwarf planet. simple way which works for orbits with a small eccentricity, like most of the planets, is to find the maximum and minimum distance from the sun. If we call the distances Dma â¦ x and Dmin, the eccentricity is given by this formula: e = (Dmax-Dmin) / (Dmax + Dmin).
