Reporter 70 miles outside of town a meteorshaped hole in the ice of a lake indicates the visitor nameless visitors last resting place. Meteorite fragments were sc scattered around likerstellar c interstellar calling cards. As if anyone would ever forget. Chelyabinsk has made history before for not being in the news. It was part of the old soviet unions Nuclear Weapons program and wa and was a closed zone, forbiddenground for ground for foreigners. Now its famous as the place where heaven and earth met withen and e a bang, anthony. Mason mark phillips. Thanks, mark. Derrick pitts is chief astronomer at the Franklin Institute in philadelphia. Derrick, what caused this huge explosion and sonic boom thats associated with this meteor . Asso and why did it cause so much damage over such a wide area . Anthony, this meteor was coming into the earths40,000 atmosphere at 40,000 miles per hour. As as it comes into the atmosphere, it has to dissipate that energy somehow and the dissipation goese di into heating the air around it as it plunges in. But it also goes into breakingeaki up the meteor, so it breaks upet into smaller pieces. That helps to dissipate thee energy. The reason why it was spread over such a large area is because the measurement on the contrail behind it is about 300ehind it i miles long. This is essentially skippingping into the atmosphere so its going to create a shock wave like a sonic boom, that rolls along the surface of the planet for quite some distance. That would create the damagee over such a wide area. Mason there was another Close Encounter today as an asteroid passed within 17,200ide the miles of earth, well inside the orbit of some of our satellites.

It just so happens in coincidence that these two events happened today. We had the one that we already knew about for quite some time and this one that just sort of shows up out of no place. If we could track the asteroid so we knew it was happening, but thats much more difficult to dots as or is. Lly a Mason Derrick pitts, thank planet you very much. In case you were wondering, an asteroid is essentially a mini planet, a piece of rock that orbits the sun. Astero a meteor is a small piece of an asteroid that enters the earths atmosphere as a shooting star. Those that hit the earth are called meteorites.
