  3. 3. Sun –Star of the Solar System• It ‘s the heaviestamong solar system• It is a ball of hot,burning gases.• It is the nearest star tothe earth.• The light from the Suntakes appx. 8 minutesto reach Earth.www.makemegenius.comFree Science Videos for Kids
  4. 4. • It is the source of all energy for life on Earth.• About three quarters of the Suns massconsists of hydrogen, while the rest ismostly helium.• On the Sun’s surface ,there are dark patchesknown as sunspots. These are patches of gasthat looks dark since they are cooler thantheir surroundings.Sun –Star of the Solar Systemwww.makemegenius.comFree Science Videos for Kids
  5. 5. • Between Inner & Outer Planets ,there is a ringof small bodies , which are made of rock &metal, these are called Asteroids. They alsokeep moving around the Sun .This ring is alsocalled Asteroids Belt.www.makemegenius.comFree Science Videos for Kids
  6. 6. Mercury –The Innermost Planet• It is named aftermessenger of theRoman gods• It is the closest planetto the Sun• Large variations in day(400 degree C) & night (-180 degree C) timetemperatures.www.makemegenius.comFree Science Videos for Kids
  7. 7. •  It is also the smallest, and its orbit is the most not fully circular.• It does not have any satellite.• There is no water or atmosphere• It can be seen with naked eyes.• It orbits the Sun once in about 88 Earth days•  There are no seasons on its surfaceMercury –The Innermost                             Free Science Videos for Kids
  8. 8. Venus –The Veiled Planet• Venus is surrounded by thick cloud cover ,that is why it is called “Veiled Planet”.• It  is brightest & hottest planet.• It is named after Roman goddess of love & beauty                             Free Science Videos for Kids
  9. 9. • It orbits the Sun once in about 225 Earth days.• Venus reaches its maximum brightness shortly before sunrise or shortly after sunset, so it is also known as the Morning Star or Evening Star.• Venus is also known as “Sister “ or “Twin” planet to earth because of its similar size & mass to earth.Venus –The Veiled                             Free Science Videos for Kids
  10. 10. Earth –The Blue Planet• It is also known as watery planet, because 70% of its surface is covered by water.• It reflects about 1/3rd of sunlight it receives .The earth’s atmosphere scatters the light & creates a blue effectn,so it is also called Blue Planet..• Only planet having life                             Free Science Videos for Kids
  11. 11. • It orbits the Sun once in about 365 Earth days.• It rotates about its own axis, thus creating day & night. It takes 24 hours to do that.• It revolves around sun, due to its tilt ,seasons are created.• Due to gravity, the layer of gases remain attached to it (which is known as atmosphere), it prevents too much heat or UV rays from Sun reaching earth.• Moon is the only satellite of the Earth.Earth –The Blue                             Free Science Videos for Kids
  12. 12. Moon –The Earth’s Only Satellite• It’s diameter of only  1/4th of the Earth•  It looks bigger to us as it is very close to us.• The moon has no atmosphere ,so there is huge difference between day & night temperature. (127 degree C in Day to -173 degree C in Night)                             Free Science Videos for Kids
