How many meteorites reach Earth in one year?

In any given year, approximately 26,000 meteorites, each weighing more than 3.5 ounces (99.2 grams) land on Earth. About 3,000 of these meteorites weigh more than 2.2 pounds (1 kilogram), according to the number of fireballs actually seen by scientists. Only a handful of these are witnessed or cause property damage; the majority of them fall into the oceans, which cover about 70 percent of Earth's surface.

On February 15, 2013, a meteorite travelling at approximately 19 miles (30 kilometers) per second exploded over Chelyabinsk, Russia. Many videos captured the image of the bright meteorite, which resulted in more than one thousand injuries, few serious (mostly from flying glass), and damage to buildings.
