THE SOLAR SYSTEM THIS PPT IS BEST FOR ALL STUDENTS

  1. 1. Submitted by- Harshit Mishra & Vinay Kachava Submitted to- Anjali dubey
  2. 2. 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
  3. 3. BIRTH OF THE SOLAR SYSTEM
  4. 4. GEOCENTRIC & HELIOCENTRIC THEORY - Ptolemaic System/ Geocentric Theory Earth centered theory - Copernican Scheme/ Heliocentric Theory Sun centered theory
  5. 5. PTOLEMAIC SYSTEM/ GEOCENTRIC COPERNICAN SCHEME/ HELIOCENTRIC
  6. 6. THE SOLAR SYSTEM The name given to the Sun and the family that orbits it. “Solar” means “of the Sun” and the sun is by far the most important member of the family. - The Sun has a “pulling force” known as “gravity” that keeps the planets flying off into space.
  7. 7. THE SOLAR SYSTEM - Solar System’s diameter is estimated to be around 1.41x10 m. or 10 light hours (1 light years= 9.46x10 m.) - The sun and the solar system is located within the outer limits of milky way galaxy. 10 12
  8. 8. MODEL OF SOLAR SYSTEM
  9. 9. The Sun  An averaged-size star Greek name: Helios Roman name: Sol Photosphere: Surface of the sun. Sunspot: cool regions
  10. 10. Categorizing Planets Terrestrial Planets Jovian Planets Smaller size and mass Higher density Solid Surface Closer to the Sun Warmer Few moons and no rings Larger size and mass Lower density No solid Surface Farther From Sun Cooler Rings and many moons
  11. 11. TERRESTRIAL PLANETS (INNER PLANET) Mercury, Venus, Earth, Mars
  12. 12. Mercury  Closest planet to the sun and the eight largest. Roman god: Mercury Greek god: Hermes (messenger of God)  Its surface is heavily cratered and very old; it has no plate tectonics.
  13. 13. 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
  14. 14. 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.
  15. 15. Moon (Luna)
  16. 16. 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
  17. 17. Moons of Mars Phobos Deimos
  18. 18. JOVIAN PLANETS (OUTER PLANET/ GAS GIANTS) Jupiter, Saturn, Uranus, Neptune
  19. 19. Jupiter  Fifth planet from the sun and by far the largest planet. Also known as Jove Greek: Zeus (the king of the gods)  it is a gas planet, which means that it does not have solid surface.
  20. 20. 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
  21. 21. Moons of Jupiter Jupiter has 62 known satellites: the four Galilean moons plus many more small ones. We’ll take a look at the four large Galilean moons which were first observed by Galileo in 1610.
  22. 22. 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.
  23. 23. 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.
  24. 24. Ganymede  Ganymede is the seventh and largest of Jupiter’s known satellites.  Ganymede has extensive cratering and an icy crust.
  25. 25. 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.
  26. 26. 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!
  27. 27. 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.
  28. 28. 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. MOONS OF URANUS
  30. 30. 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. MOONS OF NEPTUNE
  32. 32. ASTEROID BELT the region of the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. The asteroid belt is also termed the main asteroid belt or main belt to distinguish its members from other asteroids in the Solar System such as near-Earth asteroids and trojan asteroids.
  33. 33. 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 of these 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.
  34. 34. ERIS DATE OF DISCOVERY: October 21, 2003 SATALITES: 1- Dysnomia - Formerly named UB313, a kuiper belt object, officially named Eris in Sept. 13,2006 - Largest known kuiper belt object.
  35. 35. PLUTO DATE OF DISCOVERY: 1930 SATALITES: 3- Charon, Nix, Hydra - Named for the Roman god of the underworld (death). - 2nd largest Kuiper belt Object - Discovered by Clyde Tombaugh
  36. 36. HAUMEA DATE OF DISCOVERY: March 7, 2003 SATALITES: 2- Hi’iaka, Namaka - Originally called 2003 EL61 - 5th dwarf planet found by a team led by Michael Brown
  37. 37. MAKEMAKE DATE OF DISCOVERY: March 31, 2005 SATALITES: 0 - Smaller than Pluto - 4th dwarf planet found by a team led by Michael Brown - Reddish color and likely covered with frozen methane
  38. 38. CERES DATE OF DISCOVERY: January 1, 1801 SATALITES: 0 - 1st asteroid ever discovered by Guiseppe Piazzi. - Designated a dwarf planet on August 24,2006.
  39. 39. ASTEROID, METEOR, COMETS
  40. 40. 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
  41. 41. BIYO Despite often being called a planet, the lump of rock known as 13241 Biyo (1998 KM41) is actually an asteroid! Some people argue that Biyo is a minor planet (the name given to any planet smaller than a dwarf planet like Pluto), but it isn't officially classed as one. It is named after Filipino teacher Dr. Josette T. Biyo.
  42. 42. 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 planet's atmosphere  A meteorite is a meteoroid fallen to the planet’s ground.
  43. 43. 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.
