A meteor streaked through the atmosphere and exploded above the city of Chelyabinsk. The force was 20 times bigger than an atomic bomb but because it was so high in the air the effects on the ground weren’t as devastating. The same day astronomers watched an asteroid half the size of a football field make its way safely but closely past the earth. The two events weren’t connected but they did get a lot of people thinking about what’s going on outside of our planet. I wonder how big a meteor can get. I wonder how many meteors are in space. I understand that there are lots of plants in our solar system and many to be explored.
