Asteroids are different from comets and meteoroids. While asteroids are mainly composed of rock and mineral, comets are primarily composed of dust and ice. Also, asteroids formed closer to the sun, which prevents the development of cometary ice. The United States declared the 30th of June as the International Asteroid Day to educate and create more awareness about asteroids to the people.
