Just before impact, the asteroid could hit Earth at speeds of around 5.10km per second or 11,408mph (18,360km/h).
Then, at the point of contact with the planet, the asteroid would accelerate to about 12.26km per second or 27,424mph (44,134km/h).
NASA further estimates the rock weighs a staggering 500,000kg or 1.2 million pounds.
The above factors combined would result in a brute impact comparable to a small nuclear bomb being detonated.
NASA’s Sentry estimates the rock would pack the force of a 9 kiloton blast – the equivalent of 9,000 tons of TNT.
