What are asteroids? An asteroid is a large rock in outer space. Some, like Ceres, can be very large, while others are as small as a grain of sand.Due to their smaller size, asteroids do not have enough gravity to pull themselves into the shape of a ball.Astronomers group asteroids into different categories based on the way they reflect sunlight. The asteroid belt is divided into an inner belt and an outer belt.ue to their smaller size, asteroids do not have enough gravity to pull themselves into the shape of a ball.
