Asteroids
Asteroid alert! 130-foot asteroid hurtling towards Earth at warp speed
Asteroids have several shapes, they may be spherical, elongated, or oddly shaped. Some asteroids even have their own satellites! Asteroids also vary in size. From Ceres, the largest asteroid known to man which is nearly the size of the Moon to asteroids that are less than 10 meters in diameter, they can be found in all shapes and sizes. Unlike bigger asteroids which seldom stray towards Earth, smaller space rocks frequently fly past the planet at close distances.
