What is the Largest Asteroid Ever to Hit Earth?

The largest asteroid ever to reach the earth may have been divine, a Mars-sized body that formed over 4 billion years ago, during the first days of the solar system. Theia formed at a time of Lagrange, a gravitationally stable orbit around the Earth, which is opposite to the sun. Finally, the variation in pitch caused by these organizations vary ever closer to Earth, and finally that collided, throwing a large amount of ice melting in Europe today is a combination. Some molten rock throwing was so strong that cooled in orbit, composition, and became our moon. This scenario is called the giant impact theory, and explains exactly one of the characteristics of the Earth-Moon system, for example, why the moon's chemical composition is similar to that crust ..

From the Divine, the largest asteroid to impact Earth was much smaller, maxing about 10 kilometers (6 miles) in size. Larger asteroids could hit the Earth during the period called the Late Heavy Bombardment, which occurred between 4.1 and 3.8 billion years ago. Because most of the bark from this period has been pushed back and covered with a layer or layers of volcanic and sedimentary rocks, the largest crater of the asteroid can be hidden.

Confirmation largest crater on earth today is Vredefort crater in South Africa, known as the Vredefort dome or Vredefort impact structure. The crater is 300 kilometers (186 miles) with about twice the size of Chicxulub crater, left behind the asteroid that killed the dinosaurs. The Vredefort crater is considered to have been the largest asteroid impact on Earth from the moon to create one - strictly speaking, is a planet Theia a small asteroids - about 10 kilometers (6 miles) in size. In fact, the largest asteroid impact on Earth possible. So says the asteroid "the size of Texas" in films such as Deep Impact, to realize that they must use very seriously.

The Wilkes Land unusual mass concentrations during ice cover Wilkes Land in Antarctica, could mean a structural effect, but at the time of the incident, its nature uncertain.
