Asteroids a Planet Killer

The universe is the shooting field and the earth is the target. Earth is always threatened by devastating asteroids destroying civilization. More than 1000 asteroids are moving on the earth, occupying only three quarters of them. Where is the other one? Nobody knows because the government did not fund enough NASA astrologers to cover the stars. As you know, only one kind of influence can end civilization. No matter where you hit, everything will be dead even in bacteria. Estimate how much money was spent on asteroid exploration.

In the first half of the 19th century, several asteroids were discovered and classified as planets. William Herschel made the phrase "asteroid" in 1802, but other scientists called the newly discovered object the second planet. By 1851 there were 15 new asteroids, the naming process was changed to include numbers, and Ceres was designated (1) Ceres. Today, Ceres is also known as an asteroid or dwarf, but the rest is still an asteroid. Since the naming of the International Astronomical Union asteroid is not strict compared with other agencies, there is an asteroid named Frank Zappa of "Star Trek" Spock and a rock musician. . The name of the Columbia Space Shuttle crew died in 2003. You can no longer attach an asteroid to the name of a pet

Everything on the main belt is not an asteroid - Ceres, once regarded as an asteroid, is now considered a dwarf. In the past ten years, scientists have also discovered an object of the class called a small rocky object with a tail called "master asteroid." When an object strikes an asteroid or when an asteroid collapses, several tails are formed, but other tails may be camouflaged comets. Many asteroids are outside the main band. Trojan asteroids are two special places called Lagrange Points, circling around larger planets, balancing the attraction of the sun and the planet. Trojans of Jupiter are almost as many people as the main asteroid belt and are the most numerous. Neptune, Mars, there are Trojans asteroids on Earth as well

The asteroid belt is a star disk of the solar system, and it is between orbits of planet Mars and Jupiter. It is occupied by many irregularly shaped objects called asteroids or asteroids. The asteroid belt is also known as the main asteroid belt or main belt to distinguish it from other asteroid populations such as asteroids in the Earth and Trojan asteroids in the solar system. Approximately half of the quality belt is included in the four largest asteroids, Ceres, Vesta, Pallas, and Hygiea. The total mass of the asteroid belt is about 4% of the moon or 22% of Pluto, about twice the size of Pluto's monthly Karon (diameter 1200 km).
