  1. 1. The Solar System
  2. 2. The Solar System  Some scientist have debated that the solar system has formed in variety ways but however, they estimated that it was 4.6 billion years ago  It is a region of space that contains 1 star and 8 planets.  It is the Sun and all of the objects in space that orbit (go around) it. The Sun is orbited by planets, moons, asteroids, comets and other things.
  3. 3. The Sun
  4. 4. Sun  The sun is not a planet, it is a star, and it is the closest star on earth • It contains 99.9 percent of the Solar Systems mass. This means that it has strong gravity. The other objects are pulled into orbit around the Sun. • The Center of the solar system . The actual distance of sun to earth is 149.6 million kilometers.
  5. 5.  The Sun glows because of nuclear reactions in its core which turn hydrogen gas into helium.  Is a ball of hot gases. Is 70% hydrogen, 28% helium, 1.5% carbon, nitrogen, and oxygen, and 0.5% all other elements. The Suns temperature is 10,000 degrees Fahrenheit at the surface and 27,000,000 degrees Fahrenheit at the center.
  6. 6. Mercury
  7. 7. Mercury  The closest planet to the Sun, can range from 800 degrees F in the day, and at night, temperatures reach -280 F.  Mercury is the innermost and smallest planet in the solar system.  It makes one trip around the Sun once every 88 days. It orbits at 29 miles per second.
  8. 8.  It is covered in craters  The Planet Mercury is sometimes known as the Morning Star and Evening Star on Earth where it shines the brightest.
  9. 9. Venus
  10. 10. Venus  The second closest planet to the sun.  It is named after Venus, the Roman goddess of love and beauty.  It is a terrestrial planet because it has a solid, rocky surface.  Venus is considered to be the hottest of all planets in the Solar System due to greenhouse effect.
  11. 11.  Venus is covered with fastmoving sulphuric acid clouds that trap heat from the sun. Has a lot of volcanic plains with this covering almost 70% of the planet.  Temperature is about 900 F
  12. 12. Venusthe Moon, it is the  After brightest natural object in the night sky.  Venus is almost the same size as Earth.  Spins backwards on its axis. 1 Venus day equals 243 Earth days and 1 Venus year Equals 225 Earth days.
  13. 13. The Earth
  14. 14. Earth  Is the densest of all planets, also called the Blue Planet.  Earth is the only place in the universe where life has been confirmed to exist.  The Earth is home to millions of species of plants and animals, including humans.
  15. 15.  The only planet that has liquid water.  Earth has oceans of water, and an oxygen-rich atmosphere. It is made up of 75% (three quarters) water.  The distance from the surface to the center of the Earth is about 2,000 miles.  1 Earth day equals 24 hours and 1Earth year equals 365.25 days.
  16. 16. Mars
  17. 17. Mars  Mars is called the Red Planet, because of the many particles of iron oxide found on the surface of the planet.  Mars is named after the mythological Roman God of War because it is a red planet, which signifies the colour of blood.  Mars is smaller and colder than Earth. Temperatures range from 30 degrees to –220 degrees Fahrenheit.
  18. 18.  Olympus Mons, the highest known volcano within the Solar System found in the planet Mars.  Mars has two moon called Phobos and Deimos.
  19. 19.  Mars is a dry rocky planet with ice caps at its north and south poles like Earth.  1 Mars year equals 687 Earth days and 1 Mars day equals 24 hours and 39 minutes.
  20. 20. Jupiter
  21. 21. Jupiter  Has a planetary ring system and has 63 different moons.  Lo, a satellite of the planet Jupiter, is the biggest natural satellite found in the Solar System. Lo
  22. 22.  Jupiter is home to the biggest storm in the solar system, known as the Great Red Spot, located in southern hemisphere(a hurricane -like storm) which is big enough to swallow the Earth whole. • • Jupiter is so big that all the other planets could fit inside it. Jupiter is classified as a gas giant, because it is large, and is made up mostly of gas.
  23. 23. Jupiter • It is a gas giant with a mass slightly less than one- thousandth of the Sun but is two and a half times the mass of all the other planets in our Solar System combined. There are no seasons on the planet Jupiter.  Jupiter is the fastest spinning planet in the solar system completing one rotation every 10 hours.  Jupiter’s fast rotation causes the clouds to form bands.  1 Jupiter year equals 11.9 Earth years and 1 Jupiter day equals just under 10 hours. •
  24. 24. Saturn
  25. 25.  This is made up of 9 different but continuous rings which are the main rings; and there is also 3 other arcs which aren’t continuous in features.  Saturn is known as the “ringed” planet.  Rings are made of ice and rock, consisting mostly of ice particles with a smaller amount of rocky debris and dust.
  26. 26.  Saturn has 33 moons so far. Titan is the largest moon.  Titan is also bigger than Mercury and it has its own atmosphere. It’s the only moon in the entire Solar System to be able to have this.
  27. 27. Saturn  Winds at the equator reach speeds of 1,100 miles per hour.  Saturn looks like it has stripes because it is made of different gases. Some of the gases do not mix and when Saturn spins, high winds blow the gases into stripes.  We can see Saturn with a telescope but we need a small telescope to see its rings  1 Saturn year equals 29.5 Earth years and 1 day equals 10hours
  28. 28. Uranus
  29. 29. Uranus  Named after the father of Saturn in Roman mythology.  It is a light-blue gas giant because of methane gas in its atmosphere.  Uranus is the coldest planet in the solar system.  The planet is made of ice, gases and liquid metal covered with clouds.
  30. 30.  Uranus has a thin belt of 11 rings made up of rock and dust.  As well as its own magnetosphere; along with 27 moons known so far. Oberon is the largest moon.
  31. 31.  Uranus has extreme seasons with extremely dark and cold years followed by extremely hot years. Lasted for 42 years  The planet orbits the Sun only once for every 84 Earth years which is a length period of time to orbit the Sun.
  32. 32. Neptune
  33. 33. Neptune  Neptune has almost 17 times more mass than that found on Earth  Neptune has four rings which are hard to see from the Earth.  It was named after the Roman God of the Sea.  Neptune At times in its orbit it trades places with Pluto and becomes the 9th planet.
  34. 34.  Neptune also has a storm much like Jupiter. Neptune’s storm is called its Great Dark Spot.  Also has rings. These rings are made up of dark rock and dust. One of the rings even has a twist in it.
  35. 35.  Neptune has 13 moons. 1 of them, called Triton.  Triton circles the planet backwards.  1 year on Neptune equals 165Earth years and 1 day equals 22hours.
  36. 36. Eris MakeMake Pluto Haumea Ceres

Diameter: 2400? Km Temperature: 42.5 K 1 known moon Dysnomia . Named for Greek goddess of discord
  42. 42. Comets  Comets are small cosmic bodies that have an ellipsoidal orbit around the sun  Composed of rock, dust, ice, and frozen gasses  Comets do not become spherical because of their low mass and gravity  Have irregular shapes because of low mass and gravity Range from 100 meters to 40 kilometres across.
  43. 43.  Gasses found on comets include Carbon Monoxide and Dioxide, Ammonia, Methane, Ethanol, and Ethane, etc  Comet Tails, as comets approach sun, solar radiation causes particles from the comet to dissipate, and peel off of comet leaving trail of dust
  44. 44. Asteroids  Asteroids are small bodies that orbit the sun  Millions of asteroids in the solar system though to be remnants of planetismals which are small bodies that weren’t large enough to grow into planets.  Many of the asteroids in the solar system are found in the asteroid belt
  45. 45. Asteroid Belt  Asteroid Belt- Contains roughly 1.5 million asteroids with a diameter larger than 1 km  The region between the orbits of Mars and Jupiter, where many asteroids are found.
  46. 46. Meteoroids  A Meteoroid is a sand to bolder sized particle in the solar system.  Its visible path of light is called a Meteor  Meteors created because of atmospheric pressure on meteoroid during entry to Earth. This creates a trail of gases and rocks which create the visible meteor that one may see.
  47. 47. Phases of Meteoroid  Meteoroid: a chunk of rock or dust in space.  Meteor: a streak of light in the sky produced by the burning of a meteoroid in Earth’s atmosphere  Meteorite: a meteoroid that has hit Earth’s surface
  48. 48. Three Types of Meteorites  Iron Meteorites  Stony-iron meteorites  Stony meteorites  Most iron meteorites are thought to be the cores of asteroids that melted early in their history. They consist mainly of iron-nickel metal with small amounts of sulphide and carbide minerals.  Stony-iron meteorites consist of almost equal amounts of ironnickel metal and silicate minerals and are amongst the most beautiful of meteorites.  The majority of meteorite falls are stony meteorites consisting mainly of silicate minerals.
