THE SOLAR SYSTEM E.doc

THE SOLAR SYSTEMIN GENERAL Solar system is by receives the system which the gravitational pull restraint the heavenly body is composed, its most wide range approximately may extend to 1 light year outside. Solar systems main member includes: Sun (star), nine planets (including Earth), innumerable planetoids, multitudinous satellite (including moon), but also has the comet, the meteor as well as the massive dust matter and the thin gaseous state matter.Solar system (solar system) is the star system which we now is at. By the sun, 8 big planets (originally have the nine planets, because Pluto is rejected for short planet), 66 satellites (original 67, Plutos satellite is rejected) as well as the innumerable planetoids, the comet and composes. The planet gets up by the sun toward the outside order is: Mercury (mercury), Venus (Venus), Earth (earth), Mars (mars), Jupiter (Jupiter), Saturn (Saturn), Uranus (Uranus), Neptune (Neptune). To a solar nearer Mercury, Venus, the Earth and Mars are called the kind of place planet (terrestrial planets). The spaceship has all carried on the survey to them, but also once landed on Mars and Venus, has obtained the important achievement. Their common characteristic is the density big (3.0 grams/cubic centimeters), volume small, rotation slow, the satellite are few, internal ingredient mainly for the silicate (silicate), has the solid outer covering. To a solar farther Jupiter, Saturn, Uranus, Neptune are called (Jovian planets). They all have the very thick aerosphere, its superficial characteristic is very difficult to understand, the general inference, they all have with the kind of place planet similar solid essence. THE MAGIC BLACK HOLE As we all know, the black hole is body which is with an extremely gravity. Even the light cant escape from it, too. When The Schwarzschild radius(史瓦西半径) of a fixed star（恒星）become small enough, even the vertical(垂直) surface emitting(发射) light can not escape, too. And then the fixed star becomes a black hole. The reason why we say it “black” is that it just like a bottomless pit. Once whatever put into it, seems cant escape from it. Since no light can escape from the black hole, we are not able to see it directly. However, we can measure it by the role and influence which it cause to the surrounding celestial to indirect observation its presence. The time warp of the fixed star changes the route of the light, which makes the route, be different from the original. Compared with other celestial bodies, the black is very special. People can not observe(观测) it directly, even the scientists can only propose various conjectures on its internal structure. The reason that makes the black hole hide itself is the Curved space-time(弯曲的时空) . According to general relativity, time and space in a gravitational field(引力场) will bend. And now, even the light spread in the shortest distance, but relatively speaking, it has bended. Whats more, the light that some fixed stars emit toward the earth can reach even the light which is emitted from the other directions may reach the earth, because of the strong gravity of the black hole. THE BEAUTIFUL GEMINIA star between Taurus(金牛星) and Cancer（巨蟹星）, called Gemini（双子星）.Gemini is the meaning of the “twins” in Latin(拉丁语).And it is the third constellation(星座) of ecliptic（黄道）, but the first to use the image as a self-symbol in ecliptic. Originally, Gemini is the image of the two men in Roman mythology(神话) ,Castor and Pollux. They are the twins son of the god Zeus（宙斯） and Leda, the queen of mortal (凡人) Sparta. Once Zeus in heaven saw Leda and was fall in love with her soon. He in order to close to her came up with a plan. And then, he expresses love to Leda. Soon, Leda gave birth to two white goose eggs. The two brother, Castor and Pollux ,look and considerate(体贴) heart were very similar. In a war, Castor died, Pollux was sad, and he begged Zeus let him become mortal in exchange for Castor reborn. Zeus was moved, so let the twins do the patron saint（守护神） of Gemini. Castor and Pollux facing each other. Pollux 35 light years（光年）from Earth, .Castor stood silvery white shade（光芒）, the Pollux stood a golden shade, it is very interesting. Diameter（直径） ten times that of the sun. Gemini is the third constellation of the zodiac, the summer solstice （夏至）when the sun from the near by with a small telescope can see an evacuation Group（疏散集团）, with over one hundred stars, a collection of 2,600 light-years away, stood a silver-white the glorious, five and so the stars luminosity. THE FAMOUS TAURUSThere are 12 Constellation in the sky。Now，l would like to tell you something about Taurus（金牛星）.Taurus is one of the biggest and obviousest Constellations In the northern hemisphere. it has a large area about 1.933% of the all-day area. Tauruss Symbol is a bull. So its shaped like a bow Taurus. There is a brightest star, it is the Tauruss right eye. We can see Cluster in tow group with the naked eye. Someone whos Eyesight is good will find 7 bright star in one of the Cluster. So in the ancient china, people call it “Seven cluster stars”（七簇星）.There is a beautiful Greek legend about Taurus. One day, Zeus is wandering in the world. When he through a country, he saw a beautiful princess. So he falls in love with her. On a sunny day, Zeus became a beautiful bull. Then princess like it very much. So she climbed onto his back. In her surprise, the bull began to fly. After a long flight, they stopped on a island. Zeus changed back a cool man and explained his love. The princess accepted him. So they lived happily. Its said that people who is the Taurus is full of energy and hard-working. ONE OF PLANETS MARS Mars is the fourth planet from the Sun in the Solar System. The planet is named after the Roman god of war, Mars. It is often described as the Red Planet, as the iron oxide prevalent on its surface gives it a reddish appearance.11 Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth. Mars rotational period and seasonal cycles are likewise similar to those of Earth. Mars is the site of Olympus Mons, the highest known mountain in the Solar System, and of Valles Marineris, the largest canyon. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Unlike Earth, Mars is now geologically and tectonically inactive.Until the first flyby of Mars occurred in 1965, by Mariner 4, many speculated about the presence of liquid water on the planets surface. This was based on
