Asteroids

Outer Space is simply full of objects floating about endlessly. Stars, planets, meteorites, comets, and many more, but one yet remains. This next object closely resembles parts from each of the previously discussed topics. These are the "tiny planets", asteroids.

The Milky Way galaxy is full of these beings. Our solar system has hundreds flying about it, most between the Sun and Jupiter. Asteroids are mostly rock or metal, but the surface of each closely resembles the appearance of comets. They are often referred to as tiny planets due to their behavior. They, like planets, orbit the sun. Asteroids travel alone, and sometimes in asteroid belts. An asteroid belt is a massive grouping of asteroids that forms a semi-circle of asteroids that orbit together. It almost resembles a large cloud of rock.
In this picture, there is an asteroid (the left), the dwarf planet Ceres (center), and the Moon (right). Note how similar each one is to the other. Asteroids, in both behavior and appearance, truly are like tiny planets, just making their way in the night sky.
