NASA’s Near Earth Object Program identifies and tracks objects that will pass nearby Earth. They display information about these objects daily, including a probability that the objects will collide with Earth. On January 6, 2012 the two objects with the highest probability of hitting Earth were named “2011 UZ255” and “2011 VG9.” 2011 UZ255 had a diameter of 75 m and a probability of 0.000 029 of colliding with Earth. 2011 VG9 had a diameter of 120 m and a probability of 0.000 002 3 of colliding with Earth.
Should you be worried that an object from space will strike Earth? If one of the objects listed above did strike Earth, is it likely that you would be affected? How much should governments invest in defending Earth against objects like asteroids?
You can look up information from the Near Earth Object Program at the following websites:
In this lesson you will explore when and how to apply odds and probabilities to help solve problems.
