Asteroid strikes mapped

NASA released the map below in November 2014. Its purpose is to show the distribution of planet-sunken celestial bodies using the Near-Earth Object Observation Program data. The map represents all perceived asteroid impacts that belong to the category 1-20 meters in diameter, i.e., the smallest celestial body.

Yellow spots are the daylight, while the blue indicates the nighttime impacts on the map. From there, it is clear that we can not hide from the asteroids because the impacts are spread evenly across the Earth’s surface.

Asteroids

An asteroid is an inferior, irregularly shaped, solid material, smaller than a dwarf planet, circling a star. Most asteroids are probably derived from the protoplanetary disk that did not form a planet when the star system formed, and some of them had their moon.

In the Earth’s solar system, most of the asteroids are in the asteroid belt, elliptical circles around the sun, between Mars and Jupiter, and the Kuiper belt, the Pluto neighborhood.

Interestingly, according to a 2009 study, sunscreen impacts the surface of asteroids faster than previously thought.

When two asteroids collide, a small family emerges from the pieces, most of which are still fresh. According to the observation, the parts’ aging process is very rapid, only 1 million years.

Meteor, meteorite

Meteors are light phenomena (commonly referred to as falling stars) created by meteoric circulating meteorites in the Earth’s atmosphere, and friction ionizes them due to their high speeds. Meteorites are regarded as tiny asteroids; their names differ only because of their size. Meteorites that do not burn in the Earth’s atmosphere and any piece reaches the earth is called a meteorite.
