Naked Science Countdown To Impact

Today we watched a video called, “Naked Science: Countdown to Impact.” This video focuses on an asteroid that is heading towards Earth in 2008 and the possible effects that an asteroid has when it collides with Earth. October 6, 2008, for the first time ever, an astronomer discovered an asteroid while it was still in space and was also able to follow it all the way up until impact. This astronomer was able to identify that this object in space was in fact an asteroid by using their Catalina Sky Survey software and taking pictures of a certain part of the sky every fifteen minutes and overlaying these pictures. Since stars remain in the same position, anything that moves becomes obvious. To confirm his suspension he emails another astronomer, this astronomer was able to confirm because his technology to track asteroids came to a conclusion that
Luckily, this asteroid had a low density, causing it to break into pieces as it was approaching and exploded midair before it could hit the surface. However, sixty five million years ago the dinosaurs were not so lucky, with an asteroid measuring six miles across, it wiped about seventy percent of all life on Earth and changed the climate with its debris. There are millions of asteroids between the belts of Mars and Jupiter and with collisions bound to happen, Jupiter will eventually hurl some toward Earth. The asteroid TC3 history can be traced back to many years ago, where two bodies collided forming TC3 and KU2. When this incident occurred, TC3 was spun in the direction of Earth, with its other half measuring at one and half miles across following. If KU2 were ever on a collision course with Earth, it will pose a serious threat. Such as the example the video provided about another asteroid on the same level as these two asteroids, hitting San Francisco, which destroyed bridges, buildings and everything within that radius of San
