Have you ever taken a closer look at the moon and thought: where did all of those craters come from? Well, those are caused by asteroids striking it creating a large, bowl-shaped cavity on the surface called a crater. However, asteroids do not just strike the moon, they tend to strike the Earth as well. Around 66 million years ago, what is said to be an asteroid thumped the Earth, and the dinosaurs were eliminated from the planet forever. The unpredictability of asteroids, the fact that they are unstoppable, and the menace of only one strike displays how the largest threat to us humans is an asteroid. Asteroids rarely ever hit, but one strike can obliterate the entire human race. A surplus in geological support points to the fact that a very large asteroid hit the Earth a long time ago. The effect created a massive explosion, as well as a crater about 110 miles wide. …show more content…
Between 1.1 and 1.9 million asteroids greater than 1 kilometer in size reside in the main asteroid belt between Mars and Jupiter (“Asteroids: In Depth” 1). Many of those drift into Earth’s orbit, and strike. One in 700,00 are the odds of perishing in an asteroid strike, according to astronomer Phil Plait (1). The odds of being struck and the amount of asteroids there actually are in space combine to create a very unpredictable hit pattern. As commented by news reporter Brooks Hays, “New analysis of Earth’s myriad craters turned up no evidence of an impact pattern. Earth is bombarded at random, the research shows” (1). Because there is no pattern in asteroid strikes, and that Earth is bombarded randomly, asteroids pose a very large threat to the human population’s presence on the planet. Preparation for such an impact should start as soon as possible because extinction of the human race could be right around the corner. In summary, a large asteroid can come along with no recognition, and by that point it is already too
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.

Lau, Madison 09.10.17 PD : 07 Cockett Science Introduction : The purpose of this lab was to see if a marble dropped from different distances would affect the width of the crater it makes in the sand. This experiment is important to the related science content because it shows how different impacts from an object can affect things when dropped, such as how big or small a crater is. According to the article, “Why do some meteorites create such huge craters?” , Gemma Lavender explained that a meteorite would not have to be large in order to have a big impact on the ground.
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
The earth is flat. Who, but a government tool, has truly seen the spherical world? The human race should not be content to sit and accept what is broadcasted to the masses. A foul conspiracy to gain power and money keeps us in the dark, and unless the truth is thrust into common knowledge, society will continue to be controlled by scheming New World Leaders. Flat earth is the truth, and lies of science and government perpetuate the myth of a spherical earth.
A fun fact that came up is that as much a 4 billion meteors fall to the Earth each day. Most of them are not significant enough for anyone to notice. Another one is that the Earth gains about a million kilograms of mass a day from meteors.
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.
An American observatory discovers a large near-Earth asteroid, or NEA. It is given the provisional designation 2044CF. Initial data suggests that the object has a three percent chance of impacting Earth. NASA assigns a team to investigate further.
Colonizing Mars, it seems like a distant achievement. Some say impossible, some say it will happen soon. Since Elon Musk has entered this field of exploration colonization of Mars has seemed even more plausible. Still, problems have surfaced to make this much more difficult than it has to be. This makes some believe this to be impossible or unlikely for the time. Despite what side you are on we can both agree that we want to advance in space exploration.
Knowing the impermanence of the Earth, do humans have a moral obligation to find and
Asteroids can be found orbiting the Sun in a belt between Mars and Jupiter; this is called the Asteroid belt or Main belt. The asteroid belt has been said to probably contain millions of asteroids that are all different. There are more than 20,000 numbered asteroids. Some times asteroids get knocked off the asteroid belt. As asteroids revolve around the Sun in elliptical orbits, Jupiter’s gravity and getting to close to Mars or another asteroid can change an asteroids path, this could send an asteroid out of the asteroid belt and into space across the orbits of other planets. An example of asteroid orbits changing is Mar’s moons Phobos and Deimos. These were asteroids that went to close to Mars and got caught in its orbit.
Over time, other scientists began finding iridium evidence at many different locations around the world that supported the Alvarez theory. In 1991, an immense meteor crater, about 110 miles in diameter, was discovered on the the Yucatán Peninsula. The crater even extended to the Gulf of Mexico. The Chicxulub Crater, as it was called, was named after a nearby village. Scientists believe the meteor that formed this massive crater was around 6 miles in diameter. It is also believed that it struck the earth at 40,000 miles per hour and released 2 million times more energy than the most powerful nuclear bomb ever detonated. This great impact would have caused so much heat that would have boiled the earth’s surface. The scorching temperatures would have caused wildfires throughout the globe and the Earth would turn into complete darkness because debris would have filled the sky. It is believed that mile-high tsunamis could have the momentum to cover the continents, which would drown multiple species of life. Massive shock waves would even have the power to trigger earthquakes and volcanic eruptions all over the planet.
When it hit the Earth, the asteroid left an enormous crater that measured 24 miles deep and 125 miles wide (Erdman). Just the impact of the asteroid destroyed the forests and landscape of the majority of North America due to its massive shock wave (Erdman). Many species went extinct when the asteroid hit, these species include dinosaurs, ammonites (certain ocean dwelling creatures), pterosaurs, and some plant groups dinosaurs, ammonites (mollusks related to the octopus and the chambered nautilus), pterosaurs, and certain plant groups. Although devastating, the asteroid did not wipe out all of the animals on Earth, it didn’t exterminate fish, frogs, turtles, birds, mammals and crocodilians (Erdman). These animals survived and evolved into the animals that exist today.... ...
First off, even though the moon wasn't necessarily the cause of Theia colliding with Earth, the collision is said to have changed Earth's physical and chemical properties. Most of the major changes fall under one broad, self-explanatory category: land formations. Common land formations include mountains, canyons, hills, land masses, and volcanoes. These land formations, along with many others, are very beneficial for us and the rest of our planet. These things we take for granted. Just think, without mountains, without canyons, without any of these things, what would we have left? Snow would be a very rare thing as it only snows in colder climates. That
Over the course of this great country’s history there have been grotesque wars, groundbreaking discoveries, and ultimately new standards set. As a nation, the United States was built on the grounds of exploration. Testing the boundaries and reaching new heights is how the U.S. became what it is today, and is what distinguishes the U.S. from other countries. Now, of course, not every person is a scientist, astronaut, or great explorer. This is nearly impossible simply due to the fact that society branches off into countless different people with varying interests, jobs, and focuses. However, this is the time for the United States to provide its space program with the funding it needs to pave the way for a brighter future for all of mankind.
