According to Yury Zaitsev, at Space Daily, an asteroid has a speed of about 55,923 miles per hour on average. Potential asteroid impacts on Earth have become a concern in recent years, with scientists suggesting the monitoring of all space objects in close proximity to the Earth.

As Space Daily explains, the total mass of all asteroids in the solar system is less than the mass of Earth's moon. Most asteroids lie in a vast ring between the orbits of Mars and Jupiter, with the main asteroid belt holding more than 200 asteroids that are larger than 60 miles in diameter.
