  • Mercury's Rotation Period
    591 words
    As you may already know Mercury is the first planet. Which makes it the closest to the sun. It is 57,900,000 km (36,000,000 mi.) Because Mercury is so close to the sun it has extreme temperature differences. Mercury's surface temperatures range from -180 C to 450 C (-290 F to 840 F). Temperatures that hot can melt iron, and other metals. The dramatic temperature difference on Mercury are not only because it is so close to the sun but, also by Mercury's surface features. The places that are the c...

    The article summarized below is from THE NATIONAL GEOGRAPHIC (issue Dec. 97) by William R. New cott. It tells about how comets are important and their effect on earth and its people. Comets are leftover scrubs of material that did not make it to planet hood in the events creating our solar system. They orbit in a perpetual Deepfreeze until some subtle gravitational nudge upsets the delicate balance. The Great Falls begins. First a snowball drifts towards the sun and steadily accelerates. As sola...
  • Very Large Meteorite
    283 words
    Asteroids Asteroids are massive lumps of rock that orbit the Sun. They can be anything up to 1000 kilometers wide and are sometimes described as minor planets. Most asteroids in the Solar System lie in a belt - the Asteroid Belt - orbiting the Sun between Mars and Jupiter, but some are orbiting relatively nearby. These nearby asteroids are called Potentially Hazardous Asteroids or PHAs because they could collide with the Earth as gigantic meteorites. Meteorites Meteorites are bits of space debri...

    You can view either a map of the Earth showing the day and night regions at this moment, or view the Earth from the Sun, the Moon, the night side of the Earth, above any location on the planet specified by latitude, longitude and altitude, from a satellite in Earth orbit, or above various cities around the globe. Images can be generated based on a full-colour image of the Earth by day and night, a topographical map of the Earth, up-to-date weather satellite imagery, or a composite image of cloud...
  • Heat And Light Of The Sun
    1,732 words
    The Sun The sun is the largest object in the solar system. It is a middle-sized star and there are many other stars out in the universe just like it. Even though it is only a middle-sized star it is large enough to hold over 1 million Earth's inside if it were hollow. The temperature on the sun is far too much for any living thing to bear. On the surface it is 10,000 degrees Fahrenheit and the core is a stunning 27,000,000 degrees Fahrenheit. But don't worry we are over 90,000 million miles away...
  • Interpretation In Support For Copernicus System
    585 words
    Position Paper". Concerning the Use of Biblical Quotations in Matter of Science"1) Is Galileo right that Joshua passage cannot be taken literally, and that some interpretation is necessary no matter which system of the world is being considered? Yes. Literal reading of Joshua will bring us to unpleasant consequences. If only Sun's and Moon's spheres will be stopped, laws of Ptolemy will be broken (f. ex. relationship between planets and Sun-Earth line). In Copernican Universe, with modern discov...

  • Heliocentric System Of Aristarchus
    363 words
    Aristarchus lived from about the year 310 B.C. to about 230 B.C. Aristarchus was the first Greek philosopher and mathematician to make sense of the solar system. Others before him thought that the Earth is a sphere and that it moves, but he was the first to understand the heliocentric theory, which states that the sun is in the middle. In 288 or 287 B.C. he followed Theophrastus as the head of the Peripatetic School established by Aristotle. Aristarchus has only one existing book that is "On the...
  • Space Weather To Terrestrial Weather

As a society we seem to be well educated about the weather occurring on our own planet but we know little of the we...
  • Swirling Eddy Of Gas And Dust
    344 words
    The universe contains huge clouds made up of very large amounts of dust and gas. About 6,000,000,000 (billion) years ago, one of these clouds began to condense. Gravitation -- the pull that all objects in the universe have for one another -- pulled the gas and dust particles together. As the dust cloud condensed, it began to spin. It spun faster and faster and flattened as it spun. It became shaped like a pancake that is thick at the centre and thin at the edges. The slowly spinning centre conde...
  • Earth To Sun Ratio
    481 words
    The earliest known measurement from the earth to sun was in 200 B.C. Aristarchus of Samos, a man of astronomy and Mathematics, made this discovery. He believed the Earth revolved around the Sun. Aristarchus of Samos used what is known today as right-angle trigonometry. By connecting Earth to Moon, Moon to Sun, and Sun to Earth, one forms a right triangle as shown below. The measure of angle "a" is 90^0; an observer on Earth can then measure the angle measure of "b". Then for one to find the dist...
  • Copernicus And Ptolemy Astronomy

He was considered one of the greatest Greek astronomers and geographers of ancient times. Very little is known about him, but he did his observations of astronomy in Alexandria, Egypt. His works are known as Almagest, which means ...
  • Sunspots And Other Properties Of The Sun
    1,162 words
    Our Sun continuously converts hydrogen into helium and with this process it provides the essentials for life processes. In doing this it controls "our climate, provides light, raises tides, and drives the food chain" (Schaefer 34). Our Sun also has influenced many beliefs now and in the past. History has documented Sun worshipping religions while many current societies use solar calendars (Schaefer 34). Because the Sun is so influential, imperfections of the Sun, such as sunspots will continue t...
  • Changes In The Earths Orbit
    353 words
    "Identify and present evidence for three natural mechanisms of climate change, any of which might have caused all or part of the long-term global warming trend observed since the late 19th century". It is often assumed that the main reasons for an increase in global temperatures since the 19th century are due to the impact of man. However further scientific research has proven that this is not always the case and we often under-estimate the power of many natural processes. 1. Sun Activity. The s...

  • Next Closest Planets To The Sun
    716 words
    The Solar System As far as we know all life depends on the sun. The light and heat of the sun play an essential role in a lot of ways. If it was not for the sun; the seasons would not change, air wouldn't circulate, clouds wouldn't form, and rain would not fall. The sun is also the main source of all food, this is because the sun powers the plants which causes photosynthesis to occur; without this process it would not be possible to produce green plants. The sun powers our source of coal and oil...
  • Earth Due To The Sun's Light
    958 words
    The Sun is the central object of the solar systems and the largest as it contains 99.9% of the total mass of the solar system. It outweighs everything else in the solar system combined by a factor of one thousand. (The Comic Perspective) The Sun is the closest star to the earth. The strong gravitational pull of the Sun holds the Earth and the other planets within the solar system in orbit. The light and heat from the sun affects all of the objects in the solar systems and even allows life to exi...

  • Earth's Atmosphere
    318 words
    Near the Earth's poles a magnificent spectacle of shimmering colored light can sometimes be seen – the aurora. The aurora is called the aurora borealis (Northern lights) and the aurora aus trails (Southern lights); it can appear as bright as a full moon. The aurora usually appears near the Earth's poles, and more northerly (or southerly) your latitude, the more impressive the displays you will see. The lights vary in color from whitish-green to deep red and take on shapes such as streamers...
