Asteroids Essay -- essays research papers

AsteroidsIn our solar system today there be over 30,000 star-shapeds flying virtu all(prenominal)y in all direction colliding with other angulars and planets, without a care active the destruction they might convey. Our planet Earth is caught right in the heart and soul of all of this action and is liable to entire extinction of any manners forms on the planet if a large enough asteroid crosses its path. whatever single asteroid has the possibility to erase thousands of years of history and destruction the human race, as we contend it. Asteroids are large or micro chunks of rock and metal flying around space up to speeds of 80 000 km/h. These chunks were believed to have formed millions of years ago during the "big do ammunition". These rocks didnt form any planets and were stuck floating around space on their own or in the gravitation of the asteroid belt out. This asteroid belt is approximately 300 million miles from the Sun and it contains thousands of asteroi ds some being miles in diameter. Another theory of the formation of asteroids is that a planet between damage and Jupiter once existed and after many years it exploded into thousands of pieces that are suave revolving around the sun in the form of an asteroid belt. Other asteroids are formed when large meteors collide with large asteroids creating to a greater extent small ones. These meteors sewer also collide with planets breaking off chunks of the crust into space. Ceres is believed to be the biggest asteroid that was in space at one point in time. Ceres was believed to be 600 miles wide, making up 1/3 of the marrow mass of all asteroids. Ceres was the first asteroid discovered and was entrap in 1801. There are two main types of asteroids the first dominates the outmost part of the belt and are found to be rich in carbon, the second group are located in the inside of the belt and are found to be rich in minerals. The average temperature of the erupt of an asteroid is appro ximately -73 degrees C. Many people dont know that over 50,000 small asteroids called meteors hit the Earth every(prenominal) year. These meteors are the impertinent layer of larger asteroids that have been chipped off or are the fold up of other planets that have detached from their positions when hit with larger asteroids. Asteroids sometimes dress with Earth when meteors flying through space collide with other asteroids in the belt causing pieces to break off and head in all directions. ... ... wide and found within 8 million kilometers of Earth. It is very verisimilar that a large asteroid will hit the Earth in the future because of the planets past experience with asteroid collisions. Scientists picture that an asteroid more than 800 m in diameter hits the Earth every million years and a smaller one hits every century. An asteroid bigger than 1 km would mean the end of about 30% of the Worlds population. This size of an asteroid would be the equivalent fit to 2 million Hiroshima bombs. This explosion would cause destruction of all bread and butter creatures within a hundred mile radius as fountainhead as blocking off the Sun with dust and rock particles for weeks or even months. Asteroids are probably the deadliest force that our solar system butt joint produce, one strike could put man back in the temperamental ages and would kill almost the entire population of our planet. It is for this reason that scientists should focus more on understanding asteroids and research more into the defense of our planet. At the hour we only know where a fraction of the asteroids out there are. The asteroid that could destroy our planet could only be a year outside(a) and we dont even know it exists.
