  8. 8. Galaxy<br />
  9. 9. Stars are found in very large clusters or groups . These clusters are called galaxies . A galaxy consists of group of groups of stars , dust , gas and other matter , bound together by a force called gravity .<br />
  10. 10. Universe<br />
  11. 11. There could be several million stars in a galaxy . All the galaxies together make up our universe .<br />
  12. 12. Constellations<br /> When seen from the Earth , some of the stars in the sky appear to be arranged in reconisable patterns . Some look like animals , some like people , while some look like objects . These patterns stars appear to make in the sky are called constellations . <br />

  17. 17. Moon<br />
  18. 18. The Moon is the Earth’s only natural satellite . It revolves around the Earth and rotates on its axis . The Moon is about 384,403 km and has an approximate diameter of 3,476 km .<br />
  19. 19. On the Moon<br />
  20. 20. There is no air , water , wind , rain or snow . The Moon has no atmosphere . There is no life on the Moon . The surface has mountain and plain lands. There are big holes called craters . These were made by meteors .<br />
  21. 21. Phases of the Moon<br />
  22. 22. The Moon does not have light of its own and reflects only the light that falls on it from the Sun . Moon does not change its shape at all . As it keeps on revolving around the Earth ,we see different parts of it lit up . This causes different shapes of the Moon called Phases of the Moon .<br />
  23. 23. Planets<br />A planet is a celestial body that orbits a star . All the planets are spherical in shape . They are non-luminious , i.e. , they do not produce light of their own . Instead , they reflect the light of the Sun that falls on them . Every planet spins on its own axis is called rotation . One complete movement around the Sun is called a revolution or planet-year.<br />
  24. 24. Mercury<br />
  25. 25. Mercury , the planet near the Sun and is the second smallest planet in the solar system , only slightly larger than the Earth’s Moon . Mercury’s surface is covered with craters . This tiny planet does not have any rings or Moon . <br />
  26. 26. Venus<br />
  27. 27. Fair but in hospitable Venus a sister planet to the Earth that is very different from our home planet . Venus does not have any Moons or rings .<br />

  33. 33. It is the largest planet in the solar system . When approached from a far , its fantastic striped atmosphere gradually reveals intriguing clouds that move around the planet . Rich in historical and cultural connections . Jupiter is the site of recent comet impacts and continuing scientific discovery . <br />

  35. 35. The sixth planet from the Sun . It has the most spectacular set of rings in the solar system . Saturn to 60 Moons in addition to its complex ring system . <br />
  36. 36. Uranus<br />
