Meteor Impacts
Meteors are very common throughout outer space. They are being whipped around our solar system in every orbit possible. Normally they are peacefully and serenely floating through space, but one just has to look at the cratered face of our moon or Jupiter's moon Callisto to see that more than a few meteor's journeys through space have been interrupted. The earth has been hit before and will be hit in the future, statistics show this. We must detect the meteors a long time before they cross paths with Earth to prevent an impact. The likelihood of a significant meteor impact in the near future is extremely small, but it is still a possibility.
The earth is just like every other planetary body in space in that it is hit by meteors frequently. Most of these meteors are small enough that they burn up in the atmosphere. A NASA FAQ website states that meteorites the size of a basketball strike Earth about once a month, with nearly 75 percent landing in water. These are completely harmless to humans. Larger asteroids with potential for major global environment changes hit once every 100,000 years on average. A NASA Impact Hazard Fact website states that a 2km diameter or larger object collides with the Earth once or twice per million years, producing a global catastrophe that would kill a substantial (but unknown) fraction of the Earth's human population. This means that a person has about one chance in 20,000 of dying as a result of this type of collision. That same website states that less than 10 percent of the estimated 2,000 or more near Earth objects that are larger than about a half-mile in diameter have been detected to date. All in all, one should be more worried about easier (and higher probability) ways to die in this world like car crashes, diseases, other natural events, and many other possibilities.
Preventing a meteor impact depends on how soon before it hits that we find it. We have the technology right now to alter most meteor orbits away from earth. But if we never discover a meteor intercepting the Earth, these meteor 'weapons' are useless. Because much less than half of all near Earth objects are still undiscovered, we most likely will not have any warning before a meteor hits.
Humans can not be the only thing that is hurting the Earth. When you really think about it, Earth goes through a lot of natural disasters, which cannot be controlled. According to an activist, Tim Haering, “Tsunamis, floods, volcanoes, earthquakes, tornadoes, wildfires, disease nature kills more than we kill each other.” Earth throws in all of these natural ...

Asteroids are tiny, airless rocky worlds orbiting around the sun and most of them are too small to be called planets, yet, some asteroids are too big too not to be acknowledged and are known as planetoids or minor planets. The mass asteroids are puny but despite their size, asteroids can be deadly. The earth has been hit by many asteroids in the past and can potentially be hit by some again. That's one reason why scientists study asteroids and find ways to avoid them from hitting us or at least predict if they are coming.
The third inaccuracy I’m pointing out is that the big asteroid is preceded by lots of little ones which hit New York City, Paris, Shanghai, etc. It is possible for the Earth to be pelted by precursors of the main asteroid, hypothetically speaking, if the initial impact with the comet sent shrapnel flying. But that shrapnel would disintegrate quickly, and most likely by the time the shrapnel reaches the Earth, very little would be left. And another thing: why do movie asteroids only target big cities? I bet upstate New York got hit
size of the object I drop, if the object has a flat side the air
When a meteor enters Earth’s atmosphere, they enter at a minimum velocity. This minimum velocity is about 11km per second (25,000 miles per hour). That is quicker then a bullet being fired from a gun. That is only the minimum; there are meteors that can get going much faster. Another comparison to this is that a space shuttle moves around the Earth roughly at about 8km per second.
Armageddon begins by showing the destruction of the Earth by an asteroid 65 million years ago, when the dinosaurs inhabited the earth. According to the narration, the asteroid is said to have been six miles wide, with the power of 10,000 nuclear weapons. The after effects were trillions of tons of dirt and rock thrown into the atmosphere, creating a blanket of dust that the sun was unable to penetrate for 1,000 years. The narrator explained that it happened once, and that it would happen again, it was only a matter of when.
The universe is a shooting gallery and earth is the bullseye. The earth is always under threat of a doomesday asteroid that will wipe out civilization. There are over one thousand asteroids traveling toward earth and only three quarters are accounted for. Where are the other one forth? No one knows because the government doesn't fund NASA astrologists enough to cover the astroids. Just one impact could end civilization as we know it. No matter where it hits everything would die, even bacteria. To give an estimate how much is spent on asteroid detection. It is said to be less than the cost to operate a single McDonald's franchise. Total disaster would occur no matter where the asteroid hit. Land, sea it doesn't matter. Ocean impact would create a number of things. First, a Tsunami(tidal wave) would be created on impact. The wave would be hundreds for feet high traveling hundreds of miles per hour. It would start to slow down crashing ashore through all coastal city. Then, finally wash up hundreds for miles inland. " The mid-Atlantic Ocean impact ranging from 400 meters to 5 kilometers in diameter. This would generate a tsunami that would sweep across the upper East Coast of the United States to the Appalachian Mountains."(Gottschalk 1) The blast of the impact would equal a 300 gigaton blast of T.N.T. Also, 2.4 seconds after impact, a small fireball with a temperature of 5000'C would sweep across long island. A land fall strike would cause total divistation. The asteroid would create a earth trembling impact causing earth quakes around the world. The binding flash will show impact and the crater would be twenty miles across. Then, a blanket of dust and debris would blanket the earth and block the sun's light. This would occur for hundreds of years and the climate would be disrupted. Global killer no matter where it hits. The end of the world is only 28 years, 10 months, 19 days, 1 hour, 45 minutes, and 39 seconds away. An asteroid named XF11 is on route to hit earth directly. October is the month and 2038 is the year. Discovered by Jim Scotti on December 6, 1997 while looking at star with the Arizona Spacewatch Group. The asteroid "is predicted to pass at a rather comfortable distance of about 600,000 miles (about 960,000 kilometers) in 2028," "reported Dr. Donald K.
He figures out which ones are coming our way, and whether or not they are a threat (Kluger 1). Astronomers estimate that one in a thousand asteroids that pass our Earth will hit us (Booth 98). This may not seem like very many, until you consider that we are hit with at least one basketball sized asteroid every day (Kluger 6). So what happens when our one sizeable asteroid a day ends up being the size of a mountain? Well, if it happened today, we would surely be dead.
Sixty-Five million years ago, 70 percent of life on Earth died. The most reasonable and possible reason this happened was an asteroid. An asteroid hit the Earth very hard, and in doing this, dirt and dust from the impact stayed in the air and it blocked out sunlight, that’s why the dinosaurs died. An asteroid is a rock from outer space. Asteroids have orbited the Sun along with the planets since the solar system formed about 4.6 billion years ago, but it’s only been 200 years since we first discovered them. Meteorites are small pieces of asteroids broken off on impact with other asteroids. Most meteorites are rusty brown on the outside, have rounded edges from melting as they go through Earth’s atmosphere, and contain iron. There are 3 different types of meteorites: stony, metallic, and stony metallic.92 percents of all asteroids are stone, 6 percent are made of iron and nickel, and the rest are a combination. Some meteorites also contain gold, copper, platinum, and carbon.
We can see global Warming as a hazard, because of this hazard, sea level begins to rise, because of this hazard, ice caps are melting, because of this hazard, we could be experiencing extreme storms, and weather, and because of this hazard, temperature are rising abnormally. With Global Warming present, we can be having tremendous happen to us, as well as the Earth, so we must protect the Earth, so humanity can live for a longer time on Earth.
The world survived another fairly large asteroid near Earth today, as Asteroid 1999 FN53 made its travel past our planet about 7:25 am EST. While its travel sparked some worries and concerns via Internet chatter that it could hit the Earth, NASA (www.nasa.gov) scientists weren’t concerned because they have been studying this asteroid for 16 years and knew it would not hit our planet.
We then have to be careful that we don't hit any Meters because if we do get hit we will all died because the ship will be ripped apart. If we are lucky enough, we could see Comet Halley. But if we do, you will be the people to see the comet Halley this close for another 75 years.
Although it is impossible to rewrite history, we still have to be careful to prevent a catastrophe like the asteroid said to have hit the earth sixty five million years ago. If there is ever a scare of an asteroid as big as the Alvarez Asteroid, one way of preventin...
