While the particles started coming and merging to make planets, there were left over pieces that did not come together. Scientist started discovering these and noticed that there are many sizes and shapes of large rock roaming and orbiting around planets and the Sun. The 'leftovers' of our solar system are called Asteroids. Asteroids are to small and irregular shaped to be planets. They also have holes and dents in them which make them irregular shaped. Just like humans no two asteroids are the same. Many people called asteroids 'minor planets'. ]]> 2018-10-25 15:15:49 UTC https://padlet.com/nelsona23/aoibd7lyi67v/wish/297000129 nelsona23 https://padlet.com/nelsona23/aoibd7lyi67v/wish/299905037 In 1801, an Italian Priest and astronomer, Giuseppe Piazzi, discovered the Asteroid Belt. This belt is located between Mars and Jupiter and is filled with over one million asteroids. During the formation of the Solar System, dust and rock was circling the Sun. Then, gravity pulled the dust and rock together to form the planets. Not all the dust and gas were used, so it created floating remains between these two planets. The Asteroid Belt is 140 million miles across and hypothetically if you flew a spacecraft through this belt, it would be almost impossible to hit an asteroid. These asteroids are hundreds of thousands meters apart. ]]> 2018-11-02 17:20:54 UTC https://padlet.com/nelsona23/aoibd7lyi67v/wish/299905037 nelsona23 https://padlet.com/nelsona23/aoibd7lyi67v/wish/299912510 Asteroids cross Earth's orbit all the time. NEA also known as 'near Earth objects', enter at least ten thousands times per day. Most of the asteroids burn up in the Atmosphere before hitting Earth. When people try to predict when the next asteroid will hit, it's hard to know due to the fact that objects enter all of the time. 
Asteroids can do a lot of damage if they actually land on our Earth. One of the largest asteroids to hit Earth was in South Africa, and landed around 2 billion years ago. Vredefort asteroid is the largest impact crater known and also the second oldest crater that people know of. This asteroid was 190 miles in diameters. (picture shown below)]]> 2018-11-02 17:33:22 UTC https://padlet.com/nelsona23/aoibd7lyi67v/wish/299912510 nelsona23 https://padlet.com/nelsona23/aoibd7lyi67v/wish/299920155 Ever since 1970, scientist have always been bringing up the fact about mining asteroids. If they could somehow mine asteroids, the value of the asteroids could make so much money. Due to the size and minerals in asteroids, scientists predict many of the asteroids could be measured into the quilliton of dollars for just one. According to NASA, they estimate this Asteroid Belt with over 200 trillion objects and if we collected all of the asteroids they would be worth so much that everyone in the world would have 100 billion dollars. But this mission would cost so much money, time and planning that it would be very difficult. Also our technology would have to be advanced to build something that mines asteroids.
