Meteor and Asteroid Impacts
Abstract
According to theory, many, many years ago, an extremely
massive meteor wiped out all of the dinosaurs from the earth.
Since then, scientists have found proof that millions of meteors
have impacted the earth. More recently however, we are still
threatened with another meteor impact, and so scientists have
been trying to find an accurate way to track and predict the
trajectory of meteors. That is pretty much what my project is
about. I have attempted to create a program that will graph the
trajectory of any meteor. A program that will be able to
accurately predict the path a meteor will be a very useful to
not only scientists, but also government officials. Using the
data produced by this program, officials can decide whether the
meteor is harmless, or to signal an evacuation.
Meteor and Asteroid Impacts 3
Background
Every now and then, a meteorite or asteroid will approach
the earth. It can then take one of three paths. It will use
the earth’s gravity and slingshot around the earth, it will go
into orbit around the earth, or it will impact the earth. Even
through the meteorite or asteroid may take one of three paths,
the probability of it impacting the earth is very low. The
point of my final project will be to write a program that will
allow me to predict the trajectory of the meteorite/asteroid.
This turns out to be a fairly difficult problem, considering I
will have to account for three bodies of mass, the earth, the
sun, and the meteorite. Thus I have the acceleration due to
gravity of the sun and the earth. Another factor of the problem
will be the direction and angle that the asteroid approaches the
earth. Will it approach from the inside of the earth’s orbi...

... able to complete everything I hoped to,
further research would be to include commands to run the program
continuously with random values so that I can compute a
probability of a collision. I also would like to do some more
experimentation in which I would start the meteor at different
positions, such as the sun side of the earth’s orbit, and at and
angle to the earth’s orbit.
I believe that if I had more time, this would be a very
interesting project to expand on, especially considering that
there are so many different things that I can do to this
program.

However, asteroids are much more deadly. If over-sized meteor can wreck buildings and injure people, then a normal sized asteroid can easily wipe out species if it lands in the right place. As mentioned before, asteroids are much bigger than meteor and much more rare. According to the “Mail Online” 12,000 years ago some type of asteroid slammed into the Northern Canada and some scientist believe that wiped off the mammoths and caused the “Younger Dryas”. Another famous event of asteroids striking, that many scientist believe, was around 65 million years ago asteroids rained and killed of all the dinosaurs 75% of all the life on earth.

In MOD’s excel workbook I have used many macros to create shortcuts to different sheets and also macros to perform various tasks. Overall using macros will speed up how fast the end user can use and navigate the sheet and also make it easier to use. I have also used auto-sum, this automatically entered in a certain formula that I had chosen. By using auto-sum I saved time by not having to enter in long formulas. I have also used an automated filter tool, this tool filters out any data that the user decides is unneeded, which will help the user as it does not show data that useless to them or is unneeded.

Statistics taking from Spain, United Kingdom, Germany and Netherlands show the majority of all bicycle accidents involve a motor-powered vehicle such as a car, bus, truck, tram, etc... [9]. In Germany in 2011, 10% of fatally injured road users were cyclists [13]. Bicycle-vehicle accident accounted for 60% of all bicycle accidents, while bicycle-pedestrian and bicycle only accidents make up 5~6% and 12~16% respectively [9]. Data presented in a report conducted in Germany stated, accidents involving collisions with vehicles accounted for 38% of all bicycle traumas while 26% of incidents involved the rider only [14]. The most common collision partner in a bicycle-vehicle accident was a
The U.S. Army Space and Missile Defense Command is working on a new active defense weapon system concept to enhance protection for combat forces and theater-level assets for the Force XXI Army. The mobile Tactical High Energy Laser, or THEL, weapon system would provide an innovative solution for the acquisition and close-in engagement problems associated with "dumb munitions" — a primary concern because counter-battery fire may not be an option in densely populated areas.

A majority of people think the space program is a lost cause, a waste of money and a risk that should not be taken. These are all exceptional reasons why we should not fund the space program, however, there are more pros than cons in the fact of the matter. In 1969 Neil Armstrong took the first steps on the moon, this was one of the immense accomplishment of the space program that will be remembered for centuries to come. We want our children to experience these events just as we did When we were kids and the space program can do just that. Space program funding should be increased because of the human's need for exploration, greater technological advances and how it could improve the lives of people on earth.

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.
