Using Computers to Model the Physics of an Asteroid Crash

This project is an experiment to set the original earth velocity in the x direction and the y direction and change them with the meteor speed / momentum. It simply tries to simulate the effects of meteorites and asteroids on the Earth and subsequent changes in the Earth's trajectory with respect to the distance and velocity of the sun. Taking into account the meteor's mass, velocity, angle, and coordinates at the impact point, the computer program calculates the resultant velocity of the earth, including the component and the resultant velocity, and calculates the Earth's trajectory Are plotted. And after the impact.

Asteroid @ home provides information on asteroids that store research data on asteroids' natural and evolutionary domains in the solar system that characterize the physical characteristics (shape, spatial orientation, rotation period) of asteroids using photometric data To astronomy field project is. Data on spatial orientation, shape, rotation cycle (Yarkovsky effect) for determining the change of orbits using thermal radiation. Cosmology @ Home is a volunteer computing project based on the BOINC platform. It was launched by the University of Illinois Urbana-Champaign astronomy science department. As of September 5, 2013, 55,957 users (106,909 computers) from 190 countries participated in this project and achieved 13,04 teraflops performance.

In the past, scientists used molecules based on Isaac Newton's classical physical model or quantum physics to study molecules on their computers, each with advantages and disadvantages. The first method allows scientists to model large molecules and the second method allows them to study chemical reactions with small molecules. The Nobel laureate is trying to combine the advantages of both, so scientists can model large molecules and understand chemical reactions.

Despite its size, asteroids can become dangerous. In the past a lot of people have attacked the earth, and in the future more people will strike our planet. This is one of the reasons scientists study the asteroids and I am anxious to learn more about their quantities, orbits and physical properties. If asteroids move in our direction, we want to know this. About 6 billion years ago, asteroids were the remains of our solar system. In the early days, Jupiter's birth prevented the planet from forming in the gap between Mars and Jupiter, causing small objects there to collide and invade asteroids seen today.

For the most part of the nineteenth century most of the discoveries about asteroids were based on research into their orbit. Most of the knowledge about the physical properties of asteroids - for example their size, shape, rotation period, composition, mass and density - have been learned since the 20th century, especially since the 1970s. Through these studies these objects changed from mere "secondary" planets to small world objects. The following discussion will follow the progress of knowledge, first focusing on asteroids as orbiting objects and then on their physical properties.
