A small, newly-discovered asteroid named 2008 TC3 is approaching Earth and chances are good that it will hit. Measuring only a few meters across, the space rock poses no threat to people or structures on the ground, but it should create a spectacular fireball, releasing about a kiloton of energy as it disintegrates and explodes in the high atmosphere above northern Sudan. However, it should be noted that the asteroid has just been discovered. Had it beenthirty meters across instead of three, it would have been acatastrophe, and one with very little warning.

Asteroids have hit the earth many times, causing major extinctions and leaving tell-tale craters?and it turns out there are gigantic craters on Mars as well. Perhaps they wiped out life there as well?
A huge gash that has been discovered on Mars has long proven is the largest known crater in our solar system?so big, that it reshaped the planet by blasting away much of the planet?s crust in the area where it hit over 4 billion years ago.
In New Scientist, David Shiga reports that this conclusion goes along with “other evidence that numerous large projectiles were careening through the inner solar system at this time, such as the Mars-sized planet that walloped the primordial Earth and formed our Moon, yet left no trace on Earth.”

A century ago, an event in far-off Siberia gave us a wake-up call. That explosive event over remote Tunguska is generally viewed by scientists as a large space rock that pierced through the atmosphere of Siberia, then detonated to flatten some 2,000 square kilometers of trees. Could modern technology stop such an event from happening today?perhaps in a crowded city?
