Could a 70 mile wide asteroid destroy earth?

When talking about asteroidal impacts, it's worth noting that the diameter of an object is not an indication of potential impact. The density and more important is the velocity at which it impacts the Earth is. However, an asteroid with a diameter of 70 miles would not destroy the Earth. The Earth has been hit by much larger objects (Theia) and survived - yet only just. A 70 mile asteroid would make a large impact but it would not destroy the Earth. A 70 mile asteroid would however, with the right velocity and angle, in all probability, wipe all life off of the Earth and cause years of non regeneration. Simple life would eventually recolonise the planet, but it would take millions of years for complex animals to evolve. So much so, that a devastation on that scale would eliminate mankind from the Universe as we know it. The asteroid that wiped out the Dinosaurs and ended their reign was a mere 10 miles in diameter and produced 2 million times more energy that our most powerful atomic bomb. So the 70 mile asteroid would not destroy the Earth but it would certainly destroy everything on it.


The earth been destroyed by a asteroid?

No, if the Earth was destroyed by an asteroid we would not be living today.


Is the earth inside the asteroid belt?

Yes, the asteroid belt starts properly after the orbit of Mars.


Can missiles destroy asteroids?

Missiles can be used to potentially deflect or break up an asteroid, rather than destroy it completely. The effectiveness of this method would depend on the size and composition of the asteroid. Efforts to develop technology for asteroid deflection are currently being researched.


Is the the moon part of the earth or an asteroid?

Theory suggests that it is a remnant of a large asteroid that struck the Earth

Do you need to aim for the asteroid?

Yes. To destroy asteroids and protect the earth you must aim for the asteroids with nukes or the laser beam house.


What will happened if the asteroid hit the earth?

Depends on its size at time of collision,the heat and vibration can destroy city country or whole world.
