Asteroid

Answer 1

An asteroid is a small, rocky, and airless celestial object that orbits the Sun. They are similar to planets but are much smaller in size and typically irregularly shaped. Most asteroids can be found in the asteroid belt, a region located between the orbits of Mars and Jupiter. However, some asteroids have orbits that cross Earth's orbit, and these are known as near-Earth asteroids. Asteroids are remnants from the early solar system and can vary in composition, ranging from rocky materials to metals. They can range in size from small boulders to several hundred kilometers in diameter.
