Around 50,000 tons of debris enter Earth’s atmosphere each year, but most disintegrate before impact. NASA predicts a large asteroid impact every 100 years, with most being small and causing no damage. The largest asteroid is Ceres, and asteroids may be leftover material from the solar system’s formation. 10 spacecraft have orbited or landed on asteroids. The last large asteroid impact was in Siberia in 1908.

About 50,000 tons (45,359 tons) of rock, metal, and other elements travel through Earth’s atmosphere each year, but most of the time they disintegrate before they can impact our planet. However, NASA expects a large asteroid to hit Earth about once every 100 years. Most of the asteroids that reach Earth are small and cause no damage. According to NASA, 556 to 2013 cases of asteroids entering the Earth’s atmosphere were recorded from 556 to 1994. The last time an asteroid larger than 55 yards (50.3 m) made its way to Earth was in Siberia in 1908; the impact destroyed 770 square miles (2,000 square km) of forest land.

The largest asteroid in our solar system is Ceres, which is located between Mars and Jupiter. It measures 590 miles (950 km) in diameter and is generally considered a dwarf planet.
According to a widely accepted theory, asteroids could be made up of leftover material from the original formation of the solar system.
There are 10 recorded cases of spacecraft orbiting and even landing on asteroids.
