The Probability of Collisions with Earth
A 27-pound stony meteorite (chondrite) from the fireball fell in Peekskill, New York, punching a hole in the rear end of an automobile parked in a driveway and coming to rest in a shallow depression beneath it. Fifteen million years ago a 1500-meter (5000 feet) asteroid or comet hit there, excavating more than a trillion tons of material and scattering it all over Europe
Asteroids: Pictures, Videos, Breaking News
David Wilkie Director of Conservation Measures, Wildlife Conservation Society Life on the Billionth Rock From the Sun I've always regarded asteroids as somewhat like dinosaurs: mildly interesting and faintly dangerous. Mark Boslough Physicist; Fellow of the Committee for Skeptical Inquiry Why Aren't We Preparing for Supervolcanoes? It isn't statistically probable that we will encounter a supervolcanic eruption within the next century (or even millennia)
How to Survive An Asteroid Collision
Have a secondary location (perhaps a cabin in the mountains or a friend or relative in a distant small town) that you can evacuate to.Since this is an asteroid you're planning an evacuation for, and not a nuclear terrorist attack, you can first attempt to evacuate by car; hopefully state official will begin evacuations days in advance so that major cities being evacuated aren't paralyzed by millions of fleeing residents.Keep survival supplies on hand that you can pack in the trunk of your car, even on the roof of your car, and if possible also in a pull-behind trailer (such as extra gasoline, considering that gas stations may be empty of gas after a massive run for fuel by hundreds of thousands of people).Pack a mountain bike for each member of your family, as well as a backpack that each person can carry on their back while riding a bike. It is estimated, however, that such hits have created many local tsunamis and brief climate changes in recorded history, without any understanding of their cause at the time
The Bible describes a deluge for 40 days and 40 nights that created a flood so great that Noah was stuck in his ark for two weeks until the water subsided. Meanwhile, Bryant contends that chevrons found (pdf) 4 miles inland from the shore of Madagascar were formed by a wave that traveled 25 miles along the coast, moving almost parallel to the shoreline

Then, NASA discovered that there is an asteroid roughly the size of Texas heading towards the Earth, and when it does hit the Earth, the planet itself and all of its inhabitants will be obliterated, worse, the asteroid will hit the Earth in 18 days

Even so, the event caused more than 1,500 people to be hospitalized with injuries, mostly from broken glass caused by a shock wave generated when the asteroid entered the atmosphere. When the Chelyabinsk asteroid landed, a few lucky breaks prevented any deaths: it was already fractured before entering the atmosphere (which made it break into smaller pieces and burn up more easily on the way down) and the largest of the pieces that did land went straight into a frozen lake
Chelyabinsk is an industrial town long held to be one of the world's most polluted areas, and the area around it hosts nuclear and chemical weapons disposal facilities. He noted that the meteor struck only 60 miles from the Mayak nuclear storage and disposal facility, which holds dozens of tons of weapons-grade plutonium
Berman What Happened in Brief According to abundant geological evidence, an asteroid roughly 10 km (6 miles) across hit Earth about 65 million years ago. Fundamentalists are defined as people who believe that the primary way of learning about nature should not be the scientific method, or compilation of evidence tested in different labs in different countries, but rather interpretation of ancient manuscripts, such as the Koran, the Old Testament of the Bible, the New Testament, or other ancient writings
Full Story Small Asteroid to Pass Close by Earth on Sunday (2014 RC) September 3, 2014 A small asteroid, designated 2014 RC, will safely pass very close to the Earth on Sunday, 7 September 2014. Full Story The First Discovered Asteroid of 2014 Collides With Earth - An Update January 3, 2014 Several sources confirm that the first discovered asteroid of 2014, designated 2014 AA, entered the Earth's atmosphere late January 1 EST over the mid-Atlantic Ocean
But what would happen if an asteroid of this size hit us? David Moore of Astronomy Ireland says this asteroid is about the same size as an aircraft carrier, but is travelling at ten times the speed of a rifle bullet.

How the Dino-Killing Chicxulub Asteroid Impact Was Found
Some researchers have explored other possible culprits for the disaster, including other impact sites, such as the controversial Shiva crater in India, or even massive volcanic eruptions, such as those creating the Deccan Flats in India. The crash would have released as much energy as 100 trillion tons of TNT, or beyond a billion times the power of the atom bombs that destroyed Hiroshima and Nagasaki

The iridium residue would have scattered all over the globe--and the massive amounts of dust raised by the impact would have blotted out the sun, and thus killed the vegetation eaten by herbivorous dinosaurs. In normal conditions, iridium is extremely rare, leading the Alvarezes to conclude that the earth was struck 65 million years ago by an iridium-rich meteorite or comet
No, Seriously, What Killed the Dinosaurs? : Discovery News
These epic floods of molten rock are thought to have spanned 200,000 square miles (the size of California, New Mexico, Arizona, And Colorado combines), and in some places they are close to two miles thick. But they're still suspiciously close together, suggesting that perhaps some great collision in the solar system sent a scatter-shot of space rocks headed our way
The theory also concluded that not only was the dinosaur extinction abrupt but may have actually only taken hours as the heat from the astroid was so intense that the atmosphere (which was oxygen rich, as mentioned in the article) literally caught on fire in a ring of death that that circled the globe. It takes Way more faith to believe the world is here by accidents that are mathematically impossible anyway, than to believe in the Biblical God! Many scientists are also Christians as well and see no conflicts with their faith
Timing of an impact New findings using high-precision radiometric dating analysis of debris kicked up by the impact now suggest the K-T event and the Chicxulub collision happened no more than 33,000 years apart. For instance, dramatic climate swings in the preceding million years, including long cold snaps in the general hothouse environment of the Cretaceous, probably brought many creatures to the brink of extinction
The Alvarezes published their findings in 1981, postulating that the thin layer of iridium was deposited following the impact of a large meteor, comet or asteroid with the earth. Scientists believe the bolide that formed it was roughly 6 miles in diameter, struck the earth at 40,000 miles per hour and released 2 million times more energy than the most powerful nuclear bomb ever detonated
They can know the trajectory and entry point a few minutes before entry...they can tell us the path it will take, but that can change depending on the shape of the rock as well as it's angle. PaulPerry 5pts I think if the goal was to truly terrorize people with this article, they wouldn't have used NYC as ground zero.Imagine the horror and terror they could generate if they predicted it was going to impact the Foxconn plant in China
He stresses that his proposal differs from an earlier hypothesis that the energy of the impact was focused around Earth to a spot directly opposite, or antipodal, to the impact, triggering the eruption of the Deccan Traps. Paul Renne, a professor in residence in the UC Berkeley Department of Earth and Planetary Science and director of the Berkeley Geochronology Center, re-dated the asteroid impact and mass extinction two years ago and found them essentially simultaneous, but also within approximately 100,000 years of the largest Deccan eruptions, referred to as the Wai subgroup flows, which produced about 70 percent of the lavas that now stretch across the Indian subcontinent from Mumbai to Kolkata
End of the dinosaur age: A depiction of a Tyrannosaur as the asteroid strikes Before the cosmic explosion, many creatures were brought to the brink of extinction by dramatic climate swings in the preceding million years, including long cold snaps. The impact was clearly the final straw that pushed Earth past the tipping point.' The asteroid collision with Earth has now been dated to 66,038,000 years ago
Evolution: Extinction: What Killed the Dinosaurs?
For months, scientists conclude, dense clouds of dust blocked the sun's rays, darkening and chilling Earth to deadly levels for most plants and, in turn, many animals. Melted Rock These pieces of once-molten rock, called impact ejecta, are evidence of an explosion powerful enough to instantly melt bedrock and propel it more than a hundred miles from its origin

The extinction wiped out more than half of all species on the planet, including the dinosaurs, bird-like pterosaurs and large marine reptiles, clearing the way for mammals to become the dominant species on Earth. Immediately after the iridium layer, there is a dramatic decline in fossil abundance and species, indicating that the KT extinction followed very soon after the asteroid hit
The asteroid, which had a diameter of about six miles struck the Yucatan peninsula and left a crater, now known as the Chicxulub, measuring 12 miles deep by 124 miles wide. The violent collision 66m years ago, which occurred in the area that is now Mexico, triggered tsunamis across the oceans, caused powerful earthquakes and released enough heat to start many fires

These observatories have identified and obtained orbital parameters for an estimated 90 percent of all asteroids in the solar system larger than 1 kilometer in diameter. An asteroid impact on land could cause vast forest fires such as the famous Tunguska event of 1908, when such an impact devastated 2,000 square kilometers of Siberian forest
