As far as recorded events, it would have to be the one known as The Tunguska Event. Recent studies have shown that Tunguska was caused by the explosion of an asteroid about 5-6 miles above the surface of the Earth. The asteroid was believed to have been about 60 meters across.
The resulting explosion was equal to a 15 megaton bomb, and occurred in remote Siberia on June 30, 1908. Thousands of square miles were laid waste, and the seismic shock wave was detected as far away as London. The explosion was so destructive, no fragments of the asteroid were ever found.

Theoretically the largest meteor ever to hit Earth was about the size of Mars.
When Earth was forming 4.5 billion years ago, it used to be 25% larger than it is today. Apparently the Mars-sized meteor hit Earth, breaking 25% of it into space, but were held by Earth's gravity. After thousands of years, these chunks of rocks slowly were formed into the Moon. This is just a theory, but it is most likely to be true.
If not the largest meteor was the size of the Moon 65 million years ago, the end of the dinosaurs. The impact covered the entire planet with clouds.

One could quibble about whether the mars sized impactor that created the moon "counts" since the earth wasn't fully formed yet. Of course, this is true by definition since the impact itself added a significant amount of its final mass. As for impacts in more recent geological times, there was a real block-buster that hit Antarctica and caused the Permian extinction, so recent theory goes. It was so big, converging shock waves at the antipode in the Siberian Steppes created such a huge volcano, that gases from it may well have done most of the killing.

The largest confirmed meteorite impact crater on the surface of the Earth is the Vredefort Ring, in southern Africa. It is 300 km in diameter, and estimated to be 2000 million years old, nearly half the age of the Earth itself. The meteorite which caused it is estimated to have been 10 km in diameter.
There are two slightly larger possible but unconfirmed impact craters at Wilkes Land in Antarctica, and somewhere in the Indian Ocean near Australia.

the historic Mayans did not expect the top of the earth in 2012, the Hopis did not expect some thing in certain of 2012, Nostradamus does no longer provide dates and that i'm no longer certain he has an asteroid verse both, and there is not any clinical prediction of this way of difficulty coming. we've lists of gadgets properly-known to be heading our way, a number of them merely 30 meters for the time of and one hundred years away. we would easily comprehend if there became some thing "higher than Mount Everest" that became merely a lengthy time period away, no longer to educate 3 years. So if the "historic prophecies" weren't genuinely made by technique of everybody historic, and the "clinical predictions" won't be able to genuinely be cutting-edge in any clinical website or reference, then what does that go away because the source for those predictions? some crackpot authors with books to promote. extremely effectively, curiously.

there's a theory which states that the moon was created when an object the size of mars impacted the earth.

In the earliest stage of earth's age,a planet collided with it and resulted in the creation of the moon.(the ejected matter orbited the earth and slowly came together to form the moon).
This event is 4 billion years old.
