Near Earth Asteroids and The End of the World

1. Near Earth Asteroids are very, very large space rocks that are about 100 m in diameter. However, none of the known asteroids are on path to hit the Earth. The closest one has been 8.8 LD away (16 billion x 8= # of miles away). I think N.E.A's could become a potential problem but as of right now, if none of them are on course to hit the Earth, we shouldn't have anything to worry about.
   
2. YES:
1. The magnetic poles are moving rapidly, causing the loss of northern lights and position of the North and South poles. --> Science
   
2. The end of the Mayan Calendar (December 21, 2012). --> Pseudoscience
   
3. The poles are going to flip upside down and degrade the Earth in 50,000 years. --> Pseudoscience
3. NO:
   
1. The only principal correlation with the modern calendar is the Haab’ that recognized there were 365 days in one solar year (it’s not clear whether the Mayans accounted for leap years)--> Science to an extent
   
2. Many people think when something ends (such as the Mayan Calendar) that something drastic is going to occur --> Pseudoscience
   
3. Media is affecting a lot of people's minds about the end of the world and asteroids, etc.--> Pseudoscience
