Asteroids are classified as small airless rocky worlds revolving around the sun. Since asteroids are too small, they have not been called planets during the time of their existence. The larger asteroids are known as planetoids or minor planets. Asteroids as a whole, their mass does not even come close to the mass of the Earths moon. This could be a reason why they have not been known as planets. Although asteroids can be seen in any part of our galaxy, most of them reside in the area between Mars and Jupiter. In this are between Mars and Jupiter, you can find close to 200 hundred asteroids larger than 60 miles in diameter. This may not seem like a lot, but that to me seems like a large abundance of asteroids to be kept together in one place at one time. As we have learned in class, asteroids are leftovers from the formation of our solar system about 4.6 billion years ago. This to me is eye opening, because with all of these asteroids floating around in our solar system, very rarely do you hear of an incident where an asteroid hits earth. This could also be because of the gravitational pull in space, which can keep the asteroids away. NASA does a very good job of keeping track of these asteroids, and can keep a close eye on any attack that can be happening. As I will explain later in the future endeavors category, NASA is in the process of using an asteroid as a defense mechanism, and also for reasons of easily…
