MINOR MEMBERS OF THE SOLAR SYSTEM ASTEROIDS Asteroids are small rocky bodies that have been likened to “flying mountains.” The largest‚ Ceres‚ is about 1000 kilometers in diameter‚ but most are only about 1 kilometer across. The smallest asteroids are assumed to be no larger than grains of sand. Most asteroids lie between the orbits of Mars and Jupiter. They have orbital periods of three to six years. Some asteroids have very eccentric orbits and travel very close to the sun‚ and a few larger

Already‚ the sun’s contribution to human energy needs is substantial — worldwide‚ solar electricity generation is a growing‚ multibillion dollar industry. But solar’s share of the total energy market remains rather small‚ well below 1 percent of total energy consumption‚ compared with roughly 85 percent from oil‚ natural gas‚ and coal. Those fossil fuels cannot remain the dominant sources of energy forever. Whatever the precise timetable for their depletion‚ oil and gas supplies will not keep up

On February 20 2012‚ me and my daughter went to the Gates Planetarium in Denver to see the showing of the Wildest Weather in the Solar System. The first thing we did was to walk around the Space Odyssey and explore some of the exhibit they had. Then we went to see the show which I must say was far more thrilling then I or my daughter could have imagined. When you first walk into the Space Odyssey you are amazed it almost looks as thought your walking on to a spaceship or what I would imagine it

We all see the sun light every day‚ once you step outside on a hot day you fell its power and how destructive and life giving it is. Solar energy is the energy of the future‚ the main problem we have is making sure it is efficient and cheap. It seems that it would be simple to capture the sun’s rays and make electricity‚ but the material that “captures” the rays is very expensive due to it having to be a really pure material; if we use materials that are not as “pure” the electric current can’t go

Earth is the only planet in our solar system that sustains life‚ and therefore one of the most intriguing planets because of its capabilities. Each of the seven other planets that orbit the same sun as Earth is interesting in its own way. Some planets share similar characteristics to those found on Earth‚ while other planets are completely different. An analysis of these terrestrial bodies‚ using comparative planetology‚ will allow us examine these qualities. However‚ before beginning such a process

"An Earth-like planet spotted outside our solar system is the first found that could support liquid water and harbor life." This comes from a NASA researcher. New life on other planets could mean so much for the future of humans. The only way to keep finding out new information about our solar system and beyond is to spend money to research it. The only way to prove that there is life on other planets is to conduct

2.5 Aspects of Solar Cell Efficiency Most of the energy that reaches a cell in the form of sunlight is lost before it is converted to electricity. The usual efficiency of these systems ranges between 10% to 15%‚ though sometimes this efficiency increases to 30% and more. Certain physical properties affect the cell efficiency which we will briefly state. 1- Reflection: Studies show that untreated silicon reflects 36% or more of sunlight that strikes it. Chemically coating and texturing the surface

Abstract: Solar energy is quite simply the energy produced directly from the sun and collected elsewhere‚ namely the Earth. Photovoltaic technology directly converts solar energy into electricity. Photovoltaic thin film solar cells are easy to handle ‚ inexpensive and also easy to use. Thin film panel is flexible and can tolerate a bullet hole without failing and can greatly increase the surface area and the absorption coefficient needed to generate electricity. This paper will discuss the advantages

Solar Energy In 1839 Alexander Edmond Becquerel discovered the photovoltaic effect which explains how electricity can be generated from sunlight. He claimed that an electrode submerged in a conductive solution would create an electric current. ‘However even after much research and development subsequent to the discovery‚ photovoltaic power continued to be very inefficient a solar cell were used mainly for the purposes of measuring light. Solar energy is radiant light and

Li‚ 1 2-16-13 Solar Energy: The Energy of the Future Our Earth’s resorvoir of resources seem to be limitless‚ but with the exponential growth of the human population; the need for efficient alternative energy sources is becoming urgent. Therefore‚ research companies and individuals are focusing on creating new energy systems. Fossil fuels are are depleting and becoming more difficult to obtain. The earth will face an energy crisis in the near future if humans are not careful with their consumption
