Asteroids 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
Asteroids In our solar system today there are over 30,000 asteroids flying around in all direction colliding with other asteroids and planets, without a care about the destruction they might convey. Our planet Earth is caught right in the middle of all of this action and is liable to entire extinction of any life forms on the planet if a large enough asteroid crosses its path. Any single asteroid has the possibility to erase thousands of years of history and wipeout the human race, as we know it
Comets and asteroids. They are some of the first celestial bodies that humans observed and truly thought about. From ancient cultures interpreting these near-Earth objects as signs of disaster, to 18th century Europeans studying their paths, to even the extinction of the dinosaurs, comets and asteroids have always been prevalent in the majority of Earth’s history. These objects have intrigued the human race for generations, and continue to do so today. These similar subjects of fascination have many
variety of space rocks. Space contains comets, asteroids, and meteors that rush through space, but don’t make it to Earth because they burn up along the way. This is due to the amount of friction that is produced on its journey through space. Comets, asteroids, and meteors are only a few objects that orbit through space and in our solar system. As a result, these various space rocks fly throughout our solar system, creating a bunch of chemistry. Comets, asteroids, and meteors are commonly put together in
The Impact of an Asteroid on Earth Asteroids sling through space, celestial debris of diverse origins, leftovers from the formation of the solar system, broken offshoots of parental asteroids or comets that have lost their glow. But if an asteroid were to smash into Earth, the result would mean a global catastrophe and life on our Planet could come to an end. The explosion would approach that of a million megatons of TNT- sixteen hundred times greater than the most powerful nuclear weapon
All it takes is one asteroid to make all life on earth go extinct. 65 million years ago one such asteroid wiped out the dinosaurs. Despite their destructive reputation, there is more to asteroids than meets the eye. Through modern scientific research we now know the origins, makeup, composition, and potential of these fascinating space rocks. Ironically, even though asteroids could be the end of humanity they could also be its savior. Asteroids are leftovers from the formation of our solar system
How can we avoid asteroids? In our everyday lives, there are a multitude of forces acting on and upon us all the time. One fundamental force is gravity. Gravity (also known as gravitational force) is the force of attraction. Every object in the world that has mass exerts a pull-otherwise known as force, on other mass ["Forces of Attraction."]. Gravitational pull increases and decreases depending on the amount of mass, and how close objects are. ["Weight, Mass and Gravity."] [See Fig 1.]. In this

minutes, three to the asteroid belt, which is where the fun began. He was there in record time, but the asteroid belt is where his skills were need dodging asteroid left and right as he went, he was almost through but then he heard a sound, something came loose in the engine bay. Then it flew out, a Whipple dual turbocharger, he still had not known it was in there, and it was gone, Dave had connected it wrong and now the engine stopped working because it had replaced the engine belt for the added horsepower
years ago, perturbing the orbits of Mars, Earth and Mercury, may have caused the demise of the dinosaurs, new models of the Solar System suggest.” The article suggests that an upset could have “disrupted the trajectories of asteroids-normally safely confined to asteroid belts-sending one or more into the Earth.” This is an easy enough idea for the general public to understand yet it is not stated if they know what caused the upset in the first place. And this is where we depend on the researchers
Observations by NASA, have shown that asteroid AG5 could hit Earth in 2040. Though there is only a 1 in 500 chance the asteroid will hit Earth, scientists, are not certain of this calculation due to their lack of knowledge of the asteroid’s mass, orbit, and material composition. Therefore, astronomers and agencies, such as the UN, are already taking action. In fact, the UN has even suggested using nuclear weapons against the asteroid. If such an asteroid were to impact a city it could result
A Meteor will Strike the Earth and Destroy All Life Forms “With millions and millions of meteors hurtling around in our solar system, there’s always a chance that one could hit Earth at any moment. But what would be the consequences and how would the Earth be affected if one does happen to hit? If an object from space hit the sea, a huge tidal wave would be formed, hundreds of meters high, which would leave most of the world under water for a period of time, destroying and killing everything
1960’s may remember how inspired they felt by NASA’s ambition to do something as amazing as walk on the moon. Today, that inspiration is found in many smaller; yet still significant, creations for NASA programs. Somebody once dreamed of capturing an asteroid, and now NASA strives to make that dream come true. For those people who stare at the sky and question the twinkling lights blinking at them, NASA endeavors to study the more advanced systems of stars by using Pluto as a scale model. Simply because
one of the most mysterious legends in the French literary history. As we can learn from the title, the story is about a little prince. He came from a very small asteroid on which there was only one rose and three volcanoes. One day, the little prince left his asteroid and began to travel in the universe. Having visited six asteroids, he came to the earth. In Sahara, he met a fox who told him that it was only with heart that one can see rightly; what was essential was invisible to the eye. Then
In addition to the NASA’s advancement of technology and knowledge, the agency has other, less apparent benefits. The major benefit is economic. Specifically, the NASA technology has been applied in civilian life so well and in so many different ways that the modern economy could not exist without it. NASA innovations have spawned/benefitted numerous companies including Tempur-Pedic, Quantum Devices Inc., Goodyear Tire and Rubber, Thikol Propulsion, and just about any company that uses satellites
Less than three centuries ago, the entire Western half of North America had been completely unexplored. Today, more than a Hundred-Million people live in the Western states. Most of the oil in America is found on the West Coast, along with dozens of major businesses and institutions. The exploration and colonization of the “Last Frontier” has greatly benefitted humanity. If just a few thousand miles of land could have such a large impact on America and the world itself, imagine what an entire planet
scientists and paleontologists began pondering how such widespread creatures disappeared. Currently, paleontologists debate the two main hypotheses of how the classic dinosaurs died: from volcanic activity or an asteroid impact. Although they result in the same outcome, the volcanic and asteroid hypotheses differ in key elements: the actual event, the environment's stress, and the impact on life. Physical evidence left behind in each scenario supports each possible explanation for the massive extinction
When I started this paper, I had many questions. I wanted to know what all the main theories of dinosaur extinction are and how many there are. I also wanted to know what factors in each theory would have killed these massive beasts. Other questions I had are: had dinosaurs been dying out before the event? Did any dinosaurs survive the Cretaceous/Tertiary (K/T) event? What religious beliefs contradict the dinosaurs’ very existence? The last question I wanted to address was whether or not an
Though most people have heard about Comets and Asteroids many are unware of what they are and more significantly, their importance to life itself. Comets and asteroids are often described as small planets differentiating in sizes, some are baseball-sized meteors while some others are about one third the size of the moon. Other common terms used to describe them are rocky and icy bodies left over from the formation of the solar system. According to Don Yeomans from the Propulsion Lab, “Initially there
There were loud sounds coming from the window and then looking closely BAM! there it was a strike of lighting and everyone was in fear. There were thunderstorms,tornadoes, and a hurricane in the same day. You may ask yourself this question where does this happen? It happens on the planet Venus. In the story “All Summer In A Day” shows us as readers how people can wait and be calm about waiting for the sun. The sun never came out for 7 years straight and it has been raining, thunderstorms, and tornadoes
