    Extractions: Original by John Blanton. Stars, except for the Sun, although they may be millions of miles in diameter, are very far away. They appear as point sources even when viewed by telescopes. The planets in our solar system, much smaller than stars, are closer and can be resolved as disks with a little bit of magnification (field binoculars, for example). Since the Earth's atmosphere is turbulent, all images viewed up through it tend to "swim." The result of this is that sometimes a single point in object space gets mapped to two or more points in image space, and also sometimes a single point in object space does not get mapped into any point in image space. When a star's single point in object space fails to map to at least one point in image space, the star seems to disappear temporarily. This does not mean the star's light is lost for that moment. It just means that it didn't get to your eye, it went somewhere else. Since planets represent several points in object space, it is highly likely that one or more points in the planet's object space get mapped to a points in image space, and the planet's image never winks out. Each individual ray is twinkling away as badly as any star, but when all of those individual rays are viewed together, the next effect is averaged out to something considerably steadier.

Jupiter is more than twice as massive as all the other planets combined (the mass of Jupiter is 318 times that of Earth). orbit : 778,330,000 km (5.20 AU ) from Sun diameter : 142,984 km (equatorial) mass : 1.900e27 kg by W. A. Mozart; I am not sure what it has to do with the planet but it is one of Mozart's best. And that is saying a lot! Jupiter (a.k.a. Jove; Greek Zeus ) was the King of the Gods, the ruler of Olympus and the patron of the Roman state. Zeus was the son of Cronus (Saturn). Jupiter is the fourth brightest object in the sky (after the Sun , the Moon and Venus ). It has been known since prehistoric times as a bright "wandering star". But in 1610 when

    http://aa.usno.navy.mil/hilton/AsteroidHistory/minorplanets.html
    
    Extractions: Return to Asteroid Masses The recent controversy over whether Pluto should be given a minor planet number and possibly be demoted from the ranks of the major planets has made me wonder about the similar controversy that occurred 150 years ago. this involved whether or not the bodies discovered between Mars and Jupiter should be considered equal to the seven other planets known at that time. Titius von Wittenburg (1766) discovered that the relative distances of the six known planets from the Sun almost fit a simple relation. The relation's problem was that it predicted there should be a planet between the orbits of Mars and Jupiter. In 1772 he published a tract proposing that a planet should exist in the gap. According to Cunningham (1988) Johann Bode, director of the Berlin Observatory so popularized this tract that the relation is now known as Bode's law. Uranus was discovered in 1781 at just the distance where Bode's Law predicted a seventh planet (including the gap between Mars and Jupiter) should be. This touched off a search for a new planet in the gap between Mars and Jupiter. The search ended on January 1, 1801 when Guiseppe Piazzi at the Palermo Observatory discovered a 'star' that had moved from its position the previous night in the constellation of Taurus (von Zach 1801) . It was found to be a body at exactly the distance predicted by Bode's Law. Two consecutive successes for a relation that has no known physics behind it.

F, 8th grade, Blacksburg Middle School, Blacksburg, Virginia, USA. 1996 Are the planets in our solar system likely to be destroyed when the sun finally burns out, and will they be destroyed by a nuclear explosion or just drift off without the sun's gravitational pull? F, 8th grade, Blacksburg Middle School, Blacksburg, Virginia, USA. 1996 I looked around on the Internet but could not find a chart showing years and number of sunspots. Do you know where I might find this information? PM, 9th grade, Blacksburg High School, Blacksburg, Virginia, USA. 1996 All objects in the universe exert a gravitational force on all others. But, the farther away an object is, the smaller is the force it exerts. (The force is inversely proportional to square of the distance from the object: e.g., twice as far away means only 1/4 the amount of force). Furthermore, the more massive the object, the greater the force it will exert on other objects (e.g., twice the mass means twice the force). So nearby, massive objects, dominate the gravitational force on something.

    Extractions: Grades 7-12 Topic: Planetary Science-Explore and Interpret Characteristics of the Planets Learning to use a chart of data can be helpful in several ways. First, a chart can provide an orderly list of individual facts. For example, if one needs to know a single datum, like Neptune's mean distance from the sun, it is easy to find. In the chart MEAN DISTANCE OF PLANETS , you would look to the left-hand column for the "Mean Distance From Sun" row, and then look across the row to the "Neptune" column. Your answer lies where row and column cross: 4,497 (millions of kilometers). A second way to use a chart is to look for trends and patterns in the data. This approach will give you "the big picture" about the set of objects the chart describes. Take a look at the chart SILHOUETTES OF THE PLANETS . The planets are shown in approximate relative sizes, and arranged according to their order from the Sun: Mercury, on the left, is the closest to the Sun and Pluto (normally) is the farthest away. The obvious pattern, moving away from the Sun, is that there are four small planets, then two huge ones, two large ones, and a final, tiny one. Please note that two characteristics are plotted in the silhouettes: diameter and distance. Diameter is to scale and distances are not to scale. To find out the real distances from the Sun, and then establish a scale we ll need to look at the data in the chart MEAN DISTANCE FROM THE SUN.

    Extractions: The Sun is a class G star, one of the cooler stars in the universe, but extraordinarily hot by our standards. It is of medium size which has allowed it to continually burn energy at a steady but relatively slow pace. Eventually the Sun will begin to run out of its fuel and balloon into a star called a red giant, but a few billion years will pass before that happens. 98% of the total mass in the solar system is in the Sun, which shows the enormity of it, and yet it takes up a miniscule portion of our galaxy, not to mention the whole universe. The Sun is fueled by a reaction called the proton-proton chain which converts the abundant Hydrogen in its core into Helium and energy in the form of light waves. While the sun is one of the major elements responsible for life on Earth, it is also extraordinarily dangerous. It has a tumultuous atmosphere and emits gamma rays among other things that human beings should not be exposed to. While, thankfully, the Earth’s ozone layer filters out most of the harmful waves, it is still very dangerous to look directly at the Sun. Galileo did so while conducting his research and was consequently almost completely blind at the end of his lifetime.

    http://www.bbc.co.uk/education/asguru/generalstudies/sciencetechnology/23paranor
    
    Extractions: Are we looking for life on other planets? In short, the answer to this question is 'yes'. Serious, scientific attempts to find extraterrestrial life and to make contact with it have been underway for many years: The cratered, apparently lifeless surface of Mars was first revealed in the 1960s during NASA's Mariner space research programme. Since then, samples of Martian soil have been analysed by Viking Lander modules that touched down on the planet's surface. The most promising site was chosen - terrain that looked liked dried-up riverbeds. Each Lander module performed a number of experiments on soil scooped up from the Martian surface. One of these added a special radioactively labelled sugar solution to the soil - any microbes present would use this for energy as they carried out respiration. The Lander was able to detect carbon dioxide gas - a sign that respiration was happening, and therefore a sign of primitive life! Quickly, the gas stopped being generated - no more than an ordinary (lifeless) chemical reaction had occurred. In many ways, this did not really surprise the scientists, as no liquid water has been found on the planet - a vital ingredient for all known life forms. In addition, the Martian atmosphere is unable to absorb any of the dangerous ultraviolet (UV) light it has, since it has no ozone. All life on the planet's surface would be killed on contact with the UV light!

    Extractions: Griffith Observatory The news is out! There will be a series of planetary alignments in the year 2000. Will the earth tilt over? No. Will tidal forces trigger earthquakes? No. Will the polar ice caps melt? No. Will you even be able to see the alignments? Not really. But a lot of people want to know what is going on, so the Griffith Observatory has established this page with all the details and links. The following is extracted from "Cosmic Doom in 2000!" by John Mosley, a feature article which appeared in the Planetarian , the journal of the International Planetarium Society , March 1996. Doom at the End of the Millennium The thought that the world will end at a massing of the five planets dates back to at least 300 B.C. Despite all we've learned a lot about the mechanics of the solar system in the last 23 centuries, ancient superstitions remain in full health. This time a massing of the planets accompanies a change of millenniuma double whammy for those who believe such coincidences are turning points in a Master Plan for Human Fate.
