TheMainBelt

Welcome to my main belt(Asteroid)page. The Asteroid is located between Mars and Jupiter. The Asteroid was discovered by Kiyotsugu Hirayama, a Japanese astronomer. The Average Temperature on a Asteroid is -100 degrees. It is 580 miles in diameter. The smallest one is only 20 feet across! In 1996, NASA(National Aeronautics and Space Administration) launched a probe near the Asteroid Belt. One Hundred years ago (1908) an object exploded about 6 miles above the Tunguska River area of Siberia. The object may have been a comet's nucleus or a large meteorite sometimes referred to as a small asteroid. Debris from the explosion flattened forests and burned an area about 50 miles across.
