Asteroids…too close for comfort?

Posted: Updated:
CHICAGO (FOX 32 News) -

How close is too close? Take a look at this asteroid "road map" created by NASA. Depicted are the orbital paths of 1400 known asteroids which crisscross our Solar System. Each of them is considered a potential danger to Earth. They are all larger than 460 feet in size and they are monitored closely by NASA's Jet Propulsion Laboratory in Pasadena, California.

Many scientists believe that an asteroid or comet caused the demise of dinosaurs by crashing into Earth. Could that happen again? The answer is yes it is possible. We have had several close calls in the past few years alone including November 8, 2011 when "YU55" a 1312 foot wide rock sailed past Earth on a path closer than the moon. Fortunately experts believe we are safe for at least the next 100 years.
