Ukrainian scientists discovered a large asteroid in late 2013 that could possibly strike the Earth on Aug. 26, 2032. If such a collision occurred, it would strike with a force 50 times greater than the largest atomic bomb.
The object, named TV135, is 1,300 feet or nearly a quarter of a mile wide. The impact of such an object would cause damage over an area of 100,000 square miles. However, the actual chance of TV135 striking Earth is only estimated at 1 in 63,000. On the Torino Scale, which is used to categorize the impact hazard of near-Earth objects, TV135 rates a 1 out of 10, which means a very small risk, but greater than zero.Learn More
Asteroids and comets differ in composition due to where they were formed. Most asteroids are the rocky remnants of failed planets created in the inner solar system, while comets formed further out where frozen gases and liquids could not be thawed by the heat of the sun.Full Answer >
The three primary types of asteroids are C-type, M-type and S-type. Asteroids are categorized according to their composition. C-type asteroids are carbonaceous, M-type asteroids are metallic and S-type asteroids are silicaceous.Full Answer >
Asteroids are formed from the leftovers of the formation of our solar system from about 4.6 billion years ago. Early on, the birth of Jupiter prevented any planetary bodies from forming in the gap between Mars and Jupiter, causing the small objects that were there to collide with each other and fragment into the asteroids seen today.Full Answer >
One interesting fact about meteorology is that it was founded by the Greeks in the 7th century BC. The Times of London printed the first daily weather forecast on Aug. 1, 1861 by Admiral Robert Fitzroy. Nicholas of Cusa was a German inventor who created the first weather instrument in the 15th century. "Twister," "The Day After Tomorrow" and "The Perfect Storm" are movies based on meteorology.Full Answer >
