Thankfully, according to US space agency NASA, there are very few asteroids hiding in the depths of space, which pose any real threat to Earth.
NASA said: “With increasing regularity, scientists are discovering asteroids and comets with unusual orbits, ones that take them close to Earth and the Sun.
“Very few of these bodies are potential hazards to Earth, but the more we know and understand about them, the better prepared we will be to take appropriate measures if one is heading our way.
“Knowing the size, shape, mass, composition and structure of these objects will help determine the best way to divert a space rock found to be on an Earth-threatening path.”
