Asteroids entering the Earth’s orbit are difficult to track as they move through space at such a rapid speed. However, through the use of sophisticated detection satellites , automatic telescopes and high-performance computers, scientists can not only detect and track asteroids (which might enter the orbit of Earth), but also calculate the chances of the asteroid hitting the Earth. Early detection can give us time to put in place safety measures to protect the Earth's population.
