Asteroid belt is a place in our solar system between mars and Jupiter’s orbit. Most of the asteroids are present in the asteroid belt. Asteroid belt is a place where there are nearly no planets accept Ceres. Asteroid belt was form nearly 4.6 billion years ago due to Jupiter’s gravity. In the early years of our solar system Jupiter’s gravity was to strong that it prevented left over materials from clumping and forming planets which made those dust particles and rocks to orbit between Mars and Jupiter’s orbit. It contains four largest asteroids of our solar system named Ceres, Vesta, Pallas and Hygiea. Total Mass of the Asteroid belt is estimated to be 3% of the moon.
