Collision Earth! book. What's the likelihood of the impact on earth of debris from outer space?. What's the likelihood of the impact on earth of debris from outer space? Even near misses can change our climate, while a major impact could be catastrophic, equivalent to that which caused the disappearance of the dinosaurs and the rise of mammalian mastery of the planet. In this fascinating survey of the great collisions and the dangerous close passes of recent and prehi What's the likelihood of the impact on earth of debris from outer space?
Collision Earth! Meteor and Comet Impacts : The Threat from Outer Space. This book grabbed my attention. It's well documented and presents scientific data of which I had no previous knowledge.
Collision Earth! Meteor and Comet Impacts : The Threat from Outer Space. After reading it I definitely am looking up into the sky a lot more! It also reminded me that their are two places on Earth most vulnerable to meteor strikes, the USA and China, and I live in one of them, China.
But meteors are not the greatest threat to life on earth, the author . Comets, of course, are even more deadly
But meteors are not the greatest threat to life on earth, the author points out. The major threats are asteroids and comets. Comets, of course, are even more deadly. Verschuur provides a gripping description of the small comet that exploded in the atmosphere above the Tunguska River valley in Siberia, in 1908, in a blinding flash visible for several thousand miles (every tree within sixty miles of ground zero was flattened)
Scientists have detected a comet 140 meters in diameter that is due for a fly-by in 2040. There is an outside chance that it could collide with Earth. The giant rock, known as AG5, has an elliptical orbit that will bring it within striking distance of our planet in 23 years. Although the chances are slim, the possibility of impact is a little too close for comfort
Burnt rocks from outer space.
A number of other asteroids and comets are expected to come close to Earth this year. Scientists are keeping a close eye on them because even the smallest rocks can be dangerous. Comets consist of a cloud of gas and a huge tail of gas, stones and particles of dust. Burnt rocks from outer space. Meteorites look like burnt rocks. Their crust is formed when the meteorite melts upon entering the Earth's atmosphere.

Space In 1994 the Comet Shoemaker-Levy was torn .
Space In 1994 the Comet Shoemaker-Levy was torn apart as it entered the planet Jupiters gravitational field, creating explosions that could be seen from Earth with a telescope. The chance that the visitor would hit and destroy the Earth worried many (in actuality it never came close), as did the prediction that the Earth would pass through the comet's tail, whose poisonous gases would kill us all (the tail was so rarefied that the danger was nil).
Meteoroids are rocky remnants of a comet or asteroid that travel in outer space, but when these objects enter Earth's atmosphere, they are considered meteors. Most (between 90 and 95 percent) of these meteors completely burn up in the atmosphere, resulting in a bright streak that can be seen across the night sky, Moorhead said
