Solar system (1)

  1. 1. By The Blog Frog
  2. 2. Solar System Planets • Mercury • Venus • Earth •Mars • Jupiter • Saturn • Uranus • Neptune
  3. 3. Mercury is a very small planet. It is the closest planet to the sun. This small planet is extremely hot during day time, but at night time the planet is freezing. Mercury no air or water so no living beings can survive. When Mercury was a young planet it was bombarded with asteroids, the planet was battered. Still the planet is battered.
  4. 4. Venus Venus if the closest planet to earth. These two planets are thought of sisters or twins. However, they are completely different. Poisonous clouds trap the sun’s heat, making Venus the hottest of all the planets. Deadly acid rain falls on a surface covered with mountains, volcanoes and lava. Venus is also different because it spins backwards. A day on Venus lasts for 243 Earth days.
  5. 5. Earth Earth is the only planet in the solar system known to have life on it. That is because on Earth there is water so the living beings can survive. If earth was closer to the sun the water would boil away. If the earth was further away, the water would freeze. While scientists search for another planet with life, Earth has different forms like animals, people and even smaller things like germs. Earth has four layers, crust, mantle, outer core and inner core. Earth is full of larva. That’s how volcanoes irrupt.
  6. 6. Mars Mars is sometimes called the red planet because of colour of the rocks and soil is reddish-brown. Mars is much colder than Earth and wind storms which turn the sky pink. Special rocket called space probes have flown to Mars and taken photographs. We now know that much of Mars is a dry rocky dessert. There used to be rivers but now the water has frozen underground.
  7. 7. Jupiter Jupiter is the king of planets. This planet is the first and largest of the giant planets made of gas. It is a huge globe of gas clouds with no solid surface. Jupiter is beautifully colours with many streaks and swirls caused my wind storms. The GREAT RED SPOT is a gigantic whirlwind which has been blowing for more than 100 years. Jupiter has 16 moons. One of the, Ganymede, is the largest moon in the solar system.
  8. 8. Saturn Saturn is known as the ring world. Saturn’s rings are bright unlike rings on other planets. Saturn is the second largest planet, like Jupiter, a gas giant with a rocky centre about the size of earth. Saturn has more moons than any other planet. So far 18 moons have been discovered. The largest moon is Titan, is covered in orange clouds and would be like a young Earth.
  9. 9. Uranus Uranus is a bluey – green ball made out of gas and water, with molten rock in its centre. Uranus was discovered in 1781. Unlike other planets Uranus orbits round the Sun tipped on the other side. It may have knocked by an asteroid, (meteoroids) of a planet. It was in 1986 when the narrow rings made of rock and black ice around Uranus were first noticed.
  10. 10. Neptune Neptune was discovered in 1846. Neptune is the smallest of the gas giants. Like Uranus, Neptune has very dark rings. It is a blue ball, with many white clouds, which are blown by the strongest winds in the Solar System. A storm, larger tan Earth, is called the GREAT DARK SPOT. Neptune has eight moons. Triton is the biggest and strangest because it orbits Neptune in the opposite direction to the other moons.
  11. 11. Pluto After Neptune was discovered, astronauts began to search for another planet. It took many years till Pluto was discovered, in 1930. Pluto is the dwarf planet. This dwarf planet in the Solar System behaves very oddly. Pluto is usually the furthest from the Sun but its orbit take sit closer than Neptune for part of its journey. Astronomers know very little about Pluto because it’s so far away but it is thought to be made of ice, gas and rock. In 1978 a moon called Charon was discovered. This moon was half the size of Pluto. If it was possible to fly to Pluto it would take 400 years!
  12. 12. Comets Scientists believe that millions of comets orbit the Sun at the edge of the Solar System. Comets are made of chunks of icy rock and gas.
  13. 13. Meteoroids Meteoroids are giant rocks that hurdle through space. When they hit planets they make large holes called craters.
  14. 14. The Asteroid Belt Asteroids are giant rocks that come in many shapes and sizes. Some asteroids may be left over pieces of planets.
