  • 9. Relative distribution of the two types of PlanetsGas giant worlds are far from the Sun Rocky worlds are close to the Sun
  • 10. Bruno was burned alive for speculating that the stars are similar sun,perhaps having planets and some of them may even harbour life. Todayit is no longer a mere speculation. In fact till now more than460 exso-planets that is planets of other stars have been discovered.Many of them are massive like Jupiter. What an irony!
  • 11. ivaSvaacaI ]%p<aI ( Origin of Universe ) : Time starts now ………
  • 12. About 460 crore years ago there was a very big and colossal gas cloud-primordial solar cloud. The cloud rotated about itself due to self gravityand began to shrink. In the center the mass accreted and becamedense. Most of the mass in the cloud concentrated at the centerresulting in the birth of sun. As the core of this sun became moremassive and denser the temperature rose to an extent thatthermonuclear reaction – fusion could take place. Sun started to shine.
  • 13. While the rest of thematerial went aroundand around the centralmass. Small dustparticles were attractedinitially by electrostaticattraction. Once thesmall rocks becamesufficiently bigger gravityalso played a part.Slowly the proto planetswere formed.
  • 14. Proto planets fused to gather toform planets like Mercury, Earthand so on. Gas giants like Jupiterand Saturn were formed by theaccretion of the light elements.The icy materials and gases likemethane became Uranus andNeptune.
  • 15. The leftover proto planets became the kuiper cloud while the left overoriginal material became the Oorth cloud. The materials that failed toaccrete into a planet due to the gravitational perturbation of Jupiterbecame asteroid belt.Initial phase of solar evolution was full of bombardments. One result ispockmark like craters on Moon, Mercury and so on. As most of thespace rocks in the inner region got exhausted the bombardmenttapered off around 3 billion years ago.On such bombardment resulted in the formation of moon. Once it waspostulated that moon could have formed due to accretion of materialsaround Earth, could have been captured or could have split from EarthRecent studies indicate that Mars like proto planet impacted onEarth and moon resulted from the debris that was thrown out.
  • 16. saaOrmaalaocaI inaima-tI ( Origin of Solar System ) :
  • 17. The formation of solar system is not pure guess work. Looking at thenight sky one can clearly see evidence of gas cloud accreting, starformation, accreting disk, planet formation.
  • 18. Activity opportunity: Powers of 10 Surface Body Radius Volume Area Earth 1 1 1 Jupiter 10x [101] 100x [102] 1000x [103] Sun 100x 10,000x 1,000,000x
  • 19. Dwarf PlanetsThe IAU currently recognises five dwarf planets—Ceres, Pluto, Haumea,Make make, and Eris.Ceres is in the asteroid belt others in the Kuiper belt.Many Kuiper Belt objects, exist in what is believed to be a vast shell oficy and rocky objects that live at the very edge of our solar system.
  • 20. After moon brightest celestial object in the night sky is Venus.
  • 21. Moon with Shinning Venus
  • 22. Venus Phases in April-May 2004
  • 23. Ptolemys system Copernicus’s systemGalileo Galilee used telescope to observe Venus. Onseeing the waxing and waning phases of Venus, justlike that of Moon, Galileo concluded heliocentric solarsystem.
  • 24. Galileo discovered the four largest moonof Jupiter on Jan 7, 1610?.In his telescope the moons appeared astiny dots. The position of the dotschanged over days and he found thatthey were orbiting Jupiter.
  • 25. Jupiter & it’s 4 Moons
  • 26. Jupiter & it’s 4 Moons
  • 27. During July 1994 a comet named Shoemaker Levy was captured byJupiter and crashed on its surface.
  • 28. Shani has beenmuch malignedplanet in Hindutradition.Actually it is oneof the beautifulplanets with itsmajestic rings.
  • 29. Actually when Galilio looked at Saturn in1610 through telescope he was stunned.He perceived Saturn to have twostructures on both side.With improved telescope in 1616 heperceived it to structure like ears to aface.1655 Huygens could discern it to be aring like structure.It was Cassani who in 1676 distinguish itto be number of rings
  • 30. Uranus also has rings, butno so grand as Saturn.13 March 1781 Uranus wasdiscovered by William Hersheland his sister Carolina. It wasthe first planet that found noplace in any bible, puran orreligious texts.
  • 31. In olden days the suddenappearance of Comets wasconsidered bad omen.Comet was called Dumketu andin various civilisations it wasimagined to be various scaryobjects.Norman king William consideredthe appearance of comet in1066 as good omen. A new stara new king was his slogan. Hefought his enemies and becamethe king of England.
  • 32. As the sun rays evaporate andmakes the tail of the comet the tailis prominent when it is nearer tosun and it always points against thesun
  • 33. flajyaaoitYaaMcao gaRihtk : (Revisiting the assumption after knowing Universal facts) AakaXasqa ga`hgaaolaaMcaa maanavaI jaIvanaavar satt pirNaama haotao : Aaxaop / ivasaMgatI »saUya- ha ga`h naahI. »caMd` ha ga`h naahI. »rahU va kotU ho vastU Aqavaa ga`h mhNaUna Aist%vaat naahIt. »pRqvaIlaa kuMDilat sqaana naahI. » Non existence of Fixed frame of reference for observation. »P`a%yaok ga`hacaa ekTyaacaa p`Baava XaaoQaNao AXa@ya. »pRqvaIcyaa praMcana gatIbaabat AnaiBa&ta. »raXaI / naxa~ yaaMcao gauNaQama- va %yaacaI AaQaarhInata.
  • 34. Moon goes around in elliptical orbit, tiltedat about 5 degree. Apogee is at 357200km and perigee is 407100 km.Light will take about 1.25 seconds to reachEarth from moon. It takes about 27 ½ days togo around Earth, but the period between eachfull moon is about 30 days.
  • 35. The relative position of Earth, Moon and Sun results in the phases.Though every new moonday moon is in line withSun, due to the tilt of itsorbit, it will not causeeclipse every new moonday.
  • 36. Eclipse seen from another planet ! Two moons ofMars occasionally cause partial eclipse andPathfinder mission captured the eclipse that tookplace in 2004.
  • 37. Zodiac signs are mere constellation falling around Sun Path
