Solar system

  1. 1. TOPIC OUTLINE• Birth of the solar system• Geocentric & Heliocentric• Solar system - Sun - Terrestrial planet Jovian planet - Asteroid belt - Kuiper belt - Dwarf Planets - Asteroid - Meteoroid, Meteor, Meteorite - Comet
  2. 2. BIRTH OF THE SOLAR SYSTEM Film showing
  3. 3. GEOCENTRIC & HELIOCENTRIC THEORY- Ptolemaic System/ Geocentric Theory Earth centered theory- Copernican Scheme/ Heliocentric Theory Sun centered theory
  5. 5. THE SOLAR SYSTEMThe name given to the Sun and the familythat orbits it. “Solar” means “of the Sun”and the sun is by far the most importantmember of the family.- The Sun has a “pulling force” known as“gravity” that keeps the planets flying offinto space.
  6. 6. THE SOLAR SYSTEM- Solar System‟s diameter is estimated to be 10 around 1.41x10 m. or 10 light hours 12 (1 light years= 9.46x10 m.)- The sun and the solar system is located within the outer limits of milky way galaxy.
  8. 8. The Sun  An averaged-size star Greek name: Helios Roman name: Sol Photosphere: Surface of the sun. Sunspot: cool regions
  9. 9. Categorizing PlanetsTerrestrial Planets Jovian Planets Smaller size and mass Larger size and mass Higher density Lower density Solid Surface No solid Surface Closer to the Sun Farther From Sun Warmer CoolerFew moons and no rings Rings and many moons
  10. 10. TERRESTRIAL PLANETS (INNER PLANET) Mercury, Venus, Earth, Mars
  11. 11. Mercury Closest planet to the sun and the eight largest.Roman god: MercuryGreek god: Hermes(messenger of God) Its surface is heavily cratered and very old; it has no plate tectonics.
  12. 12. Venus  Second planet from the sun and the sixth largest. Greek: Aphrodite (goddess of love and beauty)  It was popular thought to be two separate bodies: the morning star and evening star
  13. 13. Earth Earth is the fifth largest planet and the third from the sun. Liquid covers 71 percent of the Earth‟s surface. The Earth has one moon.
  14. 14. Moon (Luna)
  15. 15. Mars  Fourth planet from the sun and the seventh largest. Greek: Ares, the god of war  Referred to as the Red Planet  Has the most highly varied and interesting terrain of any of the terrestrial planets
  16. 16. Moons of Mars Phobos Deimos
  17. 17. JOVIAN PLANETS(OUTER PLANET/ GAS GIANTS) Jupiter, Saturn, Uranus, Neptune
  18. 18. Jupiter Fifth planet from the sun and by far the largest planet.Also known as JoveGreek: Zeus (the kingof the gods) it is a gas planet, which means that it does not have solid surface.
  19. 19. Jupiter‟s Red Spot  The Great Red Spot, a huge storm of swirling gas that has lasted for hundreds of years.  When it is in nighttime sky, Jupiter is often the brightest „star‟ in the sky
  20. 20. Moons of JupiterJupiter has 62 known satellites: the fourGalilean moons plus many more smallones.We‟ll take a look at the four large Galileanmoons which were first observed byGalileo in 1610.
  21. 21. Io Io is the fifth moon of Jupiter. It‟s the third largest of Jupiter‟s moons. Io has hundreds of volcanic calderas. Some of the volcanoes are active.
  22. 22. Europa Europa is the sixth of Jupiter‟s moons and is the fourth largest. It is slightly smaller than the Earth‟s moon. The surface strongly resembles images of sea ice on Earth. There may be a liquid water sea under the crust. Europa is one of the five known moons in the solar system to have an atmosphere.
  23. 23. Ganymede Ganymede is the seventh and largest of Jupiter‟s known satellites. Ganymede has extensive cratering and an icy crust.
  24. 24. Callisto Callisto is the eighth of Jupiter‟s known satellites and the second largest. Callisto has the oldest, most cratered surface of any body yet observed in the solar system.
  25. 25. Saturn Saturn is the second largest planet and the sixth from the sun. Roman: Saturn (god of agriculture) Saturn is made of materials that are lighter than water. If you could fit Saturn in a lake, it would float!
  26. 26. Rings of Saturn Saturn‟s rings are not solid; they are composed of small countless particles. The rings are very thin. Though they‟re 250,000km or more in diameter, they‟re less than one kilometer thick.
  27. 27. Uranus Uranus is the third largest planet and the seventh from the sun. Uranus is one of the giant gas planets.Ancient Greek: Uranus(deity of heavens) Uranus is blue-green because of the methane in its atmosphere.
  29. 29. Neptune Neptune is the fourth largest planet and the eight from the sun.Roman: Neptune(god of the sea)Greek: Poseidon Like Uranus, the methane gives Neptune its color.
  31. 31. ASTEROID BELT the region of the Solar System locatedroughly between the orbits ofthe planets Mars and Jupiter. It is occupiedby numerous irregularly shaped bodiescalled asteroids or minor planets. Theasteroid belt is also termed the mainasteroid belt or main belt to distinguish itsmembers from other asteroids in the SolarSystem such as near-Earth asteroids andtrojan asteroids.
  32. 32. KUIPER BELT The Kuiper Belt is a disc-shaped region of icy objects beyond the orbit of Neptune -- billions of kilometers from our sun. Pluto and Eris are the best known of these icy worlds. There may be hundreds more ofthese ice dwarfs out there. The Kuiper Belt and even more distant Oort Cloud are believed to be the home of comets that orbit our sun.
  33. 33. ERISDATE OF DISCOVERY: October 21, 2003SATALITES: 1- Dysnomia- Formerly named UB313, a kuiper belt object, officially named Eris in Sept. 13,2006- Largest known kuiper belt object.
  34. 34. PLUTODATE OF DISCOVERY: 1930SATALITES: 3- Charon, Nix, Hydra- Named for the Roman god of the underworld (death).- 2nd largest Kuiper belt Object- Discovered by Clyde Tombaugh
  35. 35. HAUMEADATE OF DISCOVERY: March 7, 2003SATALITES: 2- Hi‟iaka, Namaka- Originally called 2003 EL61- 5th dwarf planet found by a team led by Michael Brown
  36. 36. MAKEMAKEDATE OF DISCOVERY: March 31, 2005SATALITES: 0- Smaller than Pluto- 4th dwarf planet found by a team led by Michael Brown- Reddish color and likely covered with frozen methane
  37. 37. CERESDATE OF DISCOVERY: January 1, 1801SATALITES: 0- 1st asteroid ever discovered by Guiseppe Piazzi.- Designated a dwarf planet on August 24,2006.
  39. 39. ASTEROID Asteroids are small Solar System bodies that are not comets, and historically referred to objects inside the orbit of Jupiter. They have also been called planetoids, especially the larger ones
  40. 40. BIYODespite often being called a planet, the lump of rockknown as 13241 Biyo (1998 KM41) is actually anasteroid!Some people argue that Biyo is a minor planet (thename given to any planet smaller than a dwarf planetlike Pluto), but it isnt officially classed as one.It is named after Filipino teacher Dr. Josette T. Biyo.
  41. 41. Meteoroid, Meteor, Meteorite A meteoroid is a sand- to boulder- sized particle of debris in the Solar System. (outside the planets atmosphere) A meteor is the visible streak of light from a meteoroid that is heated as it enters a planets atmosphere A meteorite is a meteoroid fallen to the planet‟s ground.
  42. 42. COMETS A comet is an icy small Solar System body (SSSB) that, when close enough to the Sun, displays a visible coma (a thin, fuzzy, temporary atmosphere) and sometimes also a tail.
