Asteroid passing close to Earth soon!

Space rock, 2001 AV43, will pass within 650,000 miles of Earth on Monday.  This is only 2.7 times the distance from Earth to the moon.  A cosmic eyelash.  It is between 100-230 feet in diameter and has a velocity of 8,000 mph.  This is the same size as the meteor crater in Arizona created 50,000 years ago.  That meteor was 165 feet in diameter and had the force of 10 megatons of TNT!

Asteroids are large rock in outer space. Some can be very large, while others are as tiny as a grain of sand. With their smaller size, asteroids do not have enough gravity to pull themselves into the shape of a ball.  Asteroids are left over materials from the formation of the Solar System.  26 very large asteroids have been discovered, which are probably the bigger ones. There are millions of smaller ones that we have yet to discover since they are too tiny, only a mile or so across.

Scientists are also tracking two other near Earth asteroids.  2013 UD4 was spotted from Arizona when it was 230 million miles from Earth.  2013 UP8, discovered by scientists on the Big Island of Hawaii on Haleakala,  is 3.4 million miles from Earth.

Scientist don’t see any of these asteroids as foreseeable hazards to Earth.  Of these asteroids, only 2013 UP8 is considered “potentially hazardous” to Earth.  Don’t worry, comets and asteroids only hit the Earth every 100 million years or so!
