Asteroids-Fact sheet. Asteroids are one of the many small or minor rocky planetoids that are a member of the solar system and that move in elliptical orbits primarily between the orbits of Mars and Jupiter. The largest representatives of asteroids are 1 Ceres, with a diameter of about 1,003 km, 2 Pallas and 4 Vesta, with diameters of about 550 km. About 200 asteroids have diameters of more than 97 km, and thousands of smaller ones exist. The total mass of all asteroids in the solar system is muc

THE FIRST USE OF RADAR Research Methods July 4, 2003 During World War II, battles were won by the side that was first to spot enemy airplanes, ships, or submarines. To give the Allies an edge, British and American scientists developed radar technology to see for hundreds of miles, even at night. The research that went into improving radar helped set the stage for post-war research into the transistor. 1940s radar relied on a semiconductor crystal, or rectifier. Radar worked by sending out a radi

ANGELIC OVERVIEW: Angels are spirits, proclaimed St. Augustine! St. Thomas Aquinas believed that angels were pure spirit, having no matter or mass, and taking up no space; but Thomas believed angels could assume bodies at will. The purpose of angels is the same as mankind: to love and serve the Lord. However, being that angels are not material beings, and possibly from a different dimension, they can serve the Lord in many different ways. Angels have far greater will and intellect than we have

Timothy Zahn is one of Science Fiction's most renowned authors. His forte lies in his ability to tell stories with well-researched backgrounds of futuristic technologies. He is the author of thirteen science fiction novels, including Heir to the Empire, Dark Force Rising, The Last Command, Cobra, The Blackcollar, and Warhorse. His novella Cascade Point won him the Hugo Award. Zahn has created one of Science Fiction's greatest treasures in his contribution to the Star Wars saga. The amount of cr

Our Solar System at a Glance INTRODUCTION From our small world we have gazed upon the cosmic ocean for untold thousands of years. Ancient astronomers observed points of light that appeared to move among the stars. They called these objects planets, meaning wanderers, and named them after Roman deities -- Jupiter, king of the gods; Mars, the god of war; Mercury, messenger of the gods; Venus, the god of love and beauty, and Saturn, father of Jupiter and god of agriculture. The stargazers also obs

Asteroids Our Minor Planets
Asteroids: Our Minor Planets” Earth is one sole object in the universe, which everyone is familiar with. Stretching beyond this planet are several other planets in the solar system and several thousand other celestial objects also known to revolve around the sun. These minor objects are called asteroids. Asteroids are metallic, rocky objects without atmospheres that orbit the Sun. Even though they orbit the sun, they are too small to be classified as planets, so they are often referred to as m

Dealing with planets, galaxies, comets, meteors, and stars, astronomy is the science which studies the astral bodies. Astronomy also provides the basis for other physics-related sciences such as astrophysics and cosmology. The main staples of astronomy include: the solar system, nearby stars, asteroids, galaxies, and comets. The Solar System Newton's law of gravitation concluded that a force was present between the sun and each of the planets, which caused a strong attraction. The law also incl

COMETS AND ASTEROIDS Casey Witthohn English 11R-9 Elberth A quick look at the scarred face of the moon provides evidence enough to see that space is not an empty place. Small bodies of rock and frozen materials are traveling around space at all times. As far as scientists can tell, they have been since the dawn of time. These space rocks are known as asteroids, comets, and meteors. Usually, people look at them as a work of art, or a phenomenon, until they come too close. Every few years a comet

The Advancement of Computers
The Advancement of Computers Computers are one of the most important inventions ever. If computers had not been invented, technology would not be developed to its current state. Since the computers invention, society has changed drastically. Computer technology is so helpful, that it is even used to create newer, better computer equipment. Almost everything today is linked in some way, to computers. Before computers were invented, very little was known about outer space. With the technology we h

Near Earth Objects What are NEOs? Where do they come from? Do they pose any real threat to Earth? Can they provide viable space resources? All of these questions are now under investigation by planetary scientist. There are two highly recognized research programs that I will discuss with you. The Spaceguard program is sponsored and run by NASA Ames Space Science Division: Asteroid and Comet Impact Hazard. Also under the direction of Dr. Tom Gehrels the University of Arizona has the Spacewatch pr
Asteroid Defense
Asteroid Defense
Asteroid Defense When it comes down to developing a way to defend the entire planet from destruction I am all for it. A large asteroid or comet hitting the earth is not a common occurrence. But it has happened many times before and when it does happen again the asteroid may wipe out all life, including humans. If our government did develop an anti-asteroid defense system, it would not only have to protect our country, but the whole planet. If we had such technology we would first have to be very
