The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, dust and gas. The inner solar system contains the Sun, Mercury, Venus, Earth and Mars. The main asteroid belt lies between the orbits of Mars and Jupiter. The planets of the outer solar system are Jupiter, Saturn, Uranus and Neptune (Pluto is now classified as a dwarf planet).

Everything in the Solar System orbits or revolves around the Sun. The Sun contains around 98% of all the material in the Solar System. The larger an object is, the more gravity it has. Because the Sun is so large, its powerful gravity attracts all the other objects in the Solar System towards it. At the same time, these objects, which are moving very rapidly, try to fly away from the Sun, outward into the emptiness of outer space.

The result of the planets trying to fly away, at the same time that the Sun is trying to pull them inward is that they become trapped half-way in between. Balanced between flying towards the Sun and escaping into space, they spend eternity orbiting around their parent star.

The Planets orbit in the same direction (counter-clockwise looking down from above the Sun’s North Pole); all but Venus, Uranus and Pluto also rotate in that same sense. Mercury has the fastest elliptical orbit,

48 km per second. It has the shortest revolution at 88 days. Pluto has an orbital speed of 5 km per second. It takes 248 years for Pluto to make one complete revolution.

The Solar System has eight planets, arranged in order of distance from closest to farthest from the sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. Mercury is the planet closest to the sun and it's also the smallest, only slightly larger than Earth's moon. It's a planet in the solar system named after the Roman gods. The 2nd Planet in the Solar System – Venus is the second planet from the Sun, Venus is the twin size of Earth. The surface has many different mountains and volcanoes.It is name after the roman god mercury , who was the fast flying messenger of the god. Earth is the third planet closest to the solar system, and the only planet with life. The fourth planet closest to the sun is Mars and the second smallest planet in the solar system. It is named after the roman god of war. The 5th planet in the Solar System – Jupiter is a gas giant. This is the largest planet in the system our sun. This is a planet named after the god of thunder and lightning. 6th Planet in the Solar System – Saturn is the sixth planet from the Sun, Saturn is best known for its rings. It is name after roman god of agriculture. Uranus - the seventh planet in the Solar System has extremely strange and interesting features. Uranus is the first planet in the Solar System to be discovered using only a telescope. 8th planet in the Solar System – Neptune is the eighth planet from the sun, Neptune is about the same size as Uranus. It is name after the roman god of the sea

VIII/   Astronomy is the studying of the planets and the stars, and people who study astronomy are astronomers. Telescopes help people to learn about our solar system. In 1609, Galileo used one of the first telescopes to look at the night sky. He saw mountains and craters on the Moon, and four moons around Jupiter. The first telescopes were very small. Later, people made' bigger telescopes, and they discovered new planets and moons.

When Galileo looked at a bright area in the night sky, he discovered that it was made of many stars. Later, people discovered that this is the center of our galaxy, the Milky Way. For a long time, astronomers thought that the Milky Way was the only galaxy in the universe. Then in 1930, an American astronomer called Edwin Hubble discovered another galaxy. Now we know that there are billions of galaxies in the universe.

Question 1.  What is the passage mainly about?

      A. Astronomy                  B. Galileo       C. Planets                          D. The Milky Way

Question 2. According to the passage, what is true about Galileo?

      A. He used the first telescope to look at the sky.

      B. Later, he used bigger telescopes to discover other planets and moons.

      C. He discovered the existence of a galaxy, which was later known as the Milky Way.

      D. Galileo worked with Edwin Hubble to discover another galaxy.

Question 3. What does the word “it” in line 6 refer to?

      A. the star                B. the sky       C. the universe           D. the bright area in the night sky     

Question 4. According to the passage, which statement is NOT TRUE?

      A. The first telescopes were small.

      B. The Milky Way was the only galaxy in the universe.

      C. The astronomer who discovered the next galaxy after the Milky Way was an American.

      D. Our universe has billions of galaxies.

How many planets are there in our galaxy? That’s a tricky question to answer. Are there other planets that support life? That’s exactly what the Kepler mission hopes to discover.
NASA launched the Kepler space telescope, designed to find habitable planets, in 2009. So far it has discovered five new Earth-sized planets beyond our solar System. These planets are hotter than the Earth -much too hot for life as we know it. The Kepler team predict that they will need at least three years to find an Earth-like planet.The simplest requirement for a planet to have life is for there to be liquid water so the distance from the planet’s sun and therefore temperature are important. There also needs to be the correct amount of air. If a planet is as small as Mars (half the size of Earth) its weak gravity means that it can’t hold on to air molecules. If a planet is Neptune sized (four times bigger than Earth) it has very strong gravity and too much air. So size
matters too. The cost of the mission is approximately six hundred million dollars. It is scheduled to observe until 2013 but this could be extended. Will we be sad if we discover we are alone in our galaxy or happy if we find that we share it with other life forms?

Hello everyone, today I will talk about Mars, the 4th planet in our solar system. The name of Mars originally comes from the name of the Roman god of war and agriculture. It may not seem like these two things go together, but they do. Mars protected those who fought for their communities and stayed home to raise crops for food. Mars has two natural satellites, and their names are Phobos and Deimos. With a radius of 2,106 miles (3,390 kilometers), Mars is about half the size of Earth. The atmosphere of Mars is much thinner than Earth's. It contains more than 95% carbon dioxide and much less than 1% oxygen.  Mar's temperatures are from -151°C to 20°C. Mars is colder than Earth. If you were to stand on the surface of Mars on the equator at noon, it would feel like spring at your feet and winter at your head. Mar's surface is rocky, with canyons, volcanoes, dry lake beds and craters all over it. It's called Red Planet because iron minerals in the Martian soil oxidize, or rust, causing the soil and atmosphere to look red. One day on Mars takes a little over 24 hours. Mars makes a complete orbit around the Sun in 687 days. Thanks for listening.
