3 The learner will be able to :  define Solar System.  know about physical properties of planets.  describe about life on Earth.  distinguish between Asteroids and Comets.

4 The solar system consists of the SUN; the nine planets, over 100 satellites of the planets, the comets and asteroids, and the interplanetary medium.cometsasteroids,

5 The Sun is by far the largest object in the solar system. It contains more than 99.8% of the total mass of the Solar System There are nine planets and a large number of smaller objects orbiting the Sun.

6 8.NeptuneNeptune Mercury 4.MarsMars 9.PlutoPluto 6.SaturnSaturn 5. JupiterJupiter 2.VenusVenus 3. Earth Earth 7.UranusUranus 1.

7 Mercury is the closest planet to the Sun and the eighth largest. In Roman mythology Mercury is the God of commerce, travel and thievery. Mercury has no known satellites. Orbit: 57,910,000 km (0.38AU) from Sun Density: 4,880 km Mass: 3.30e23 kg

8 Venus is the second planet from the Sun, the sixth largest and the brightest. It is also regarded as Earth’s sister planet. Venus is called the Goddess of love and beauty. It rotates from east to west. Orbit: 108,200,000 km Diameter : 12,103.6 km Mass: 4.869e24 kg

9 Earth is the third planet from the Sun,the fifth largest: and the densest major body in the Solar System having life on it..having life on it... In Roman Mythology, the Goddess of the Earth was TELLUSs - the fertile soil. 71 Percent of the Earth's surfaces is covered with water. Earth has only one natural water satellite, the Moon. Orbit 149,600,000 km from Sun Diameter 12,756.3 km Mass 5.972e24 kg

10 Mars is the fourth planet from the Sun and the seventh largest. Mars is the God of War. Mars has permanent ice caps at both poles composed mostly of solid carbon dioxide ("dry ice"). Orbit: 227,940,000 km from Sun Diameter :6,794 km Mass:: 6.4219e23 kg

11 Jupiter is the fifth and the largest planet from the Sun. Jupiter is more than twice as massive as all the other planets combined. Jupiter was the King of the Gods, The Great Red Spot has been seen by Earthly observers for more than 300 years. Jupiter has rings like Saturn's, but much fainter and smaller. Orbit: 778,330,000 km) from Sun Diameter : 142,984 km Mass:: 1.900e27 kg

12 POSITION:2 nd largest,least dense,sixth planet of the solar system with very bright and thin rings. Known as God Of Agriculture in Roman Mythology. Diameter:: 120,536 km. Mass : 5.68e26kg. Satellites: 18 named satellites.

13 Position:3 rd largest,seventh planet of solar System. Appears to be blue in colour,has bands of clouds,has rings and is a gas planet. 20 named moons and 1 recently discovered. Diameter : 51,118km. Mass: 8.683e25kg.

14 POSITION : 4 TH largest,eighth planet of the Solar System. Known as “God Of The Sea” Diameter : 49532km. Mass: 1.0247e26kg.

15 Position :Smallest and farthest planet.Known as “God Of The Underworld” in Roman Mythology.Discovered in 1930 and has one satellite, Charon. Diameter :2274 km. Mass: 1.27e22kg.

16 Comets have more volatile and more elliptical orbits than asteroids.Known as “Dirty Snowballs” or “Icy Mudballs”.They develop a tail as they approach the Sun pointing away from Sun. Example. COMET HALLEY.

17 POSITION: Mostly between Mars and Jupiter. Known as Minor Planets or Planetoids. No. of Asteroids with diameter greater than 200km. = 26. LARGEST ASTEROID: 1 Ceres,933 km.diameter. Castalia Eros

18 Is believed to have begun about 3500 million years ago in the salty waters of the sea.

19 Liquid Water is essential for life as we know it.71% of earth’s surface is covered with water in the form of oceans,,polar ice, glaciers,rivers and lakes.oceans,glaciers

20 The distribution of Water on Earth: 97.308%- oceans,seas,salt lakes, 0.61% underground reservoirs, 0.009% lakes, 0.005% soil as moisture …

21 Glaciers and Polar ice contains 2.02%, atmosphere as vapour 0.001% and rivers 0.0001% of water on Earth.

22 Our job is to go on trying to know more and more about the Universe. This search can never end,though we know,yet we must not give up.In the words of Isaac Newton __ “The true delight is in the finding out rather than in the knowing.”
