No, an asteroid cannot travel at the speed of light. According to the theory of relativity, the speed of light in a vacuum, denoted by 'c', is the ultimate speed limit in the universe. Nothing with mass can reach or exceed the speed of light.
Asteroids, like other objects with mass, are subject to the laws of physics and cannot travel at speeds equal to or greater than the speed of light. They typically move at significantly slower speeds, even when influenced by gravitational forces. The velocities of asteroids in our solar system can vary widely depending on their orbits and interactions with other celestial bodies, but they are always much lower than the speed of light.
