This is a HIGHLY useful website. It tells people of the Near Earth Object threats. Like Asteroids and Meteors that may impact the earth. Currently there are 2 listed. Anything in color(excluding white and light blue) are NEO's that pose a threat to the earth with in the next 100 years. So to sum it up its: White/Blue: No issue. Green: Go about your day but be aware. Yellow: Stay tune. Orange: Start to worry. Red: Say your goodbyes and do what you always wanted to do, because WE ARE ALL GOING TO DIE! I'm hoping for a Red.
