Mars is the fourth planet from the sun.Mars is also called the Red planet because its surface appears red.The red color of Mars is caused by the presence of hydrated iron oxide compound on its soil.

Of all of the planets, Mars is most like the Earth.Mars is a rocky planet. Mars has a thin atmosphere as compared to the Earth. The thin atmosphere of mars contains mainly carbon dioxide with small amounts of nitrogen, oxygen, noble gases and water vapour.

Slide 27

Since the planet Mars is very far off from the Sun, so it is quite cold planet. The surface temperature on Mars varies from a minimum of, -87°c to a maximum of 17°c. It has no water. The atmosphere of mars is so thin that it allows the deadly ultra violet rays of the sun to reach its surface.Though no evidence of the existence of any form of life on mars has been found so far but investigations are still going on.Mars has two natural satellites called ‘phobos’ and ‘Deimos’.

Jupiter

Jupiter is the fifth planet from the earth.Jupiter is the biggest planet of the solar system.The diameter of Jupiter is 11 times the diameter of the Earth and mass is about 318 times that of the Earth.Because of its very big size, Jupiter can be seen easily in the night sky.Jupiter is made mainly of hydrogen and helium gases. Jupiter has a very deep atmosphere . The atmosphere of the Jupiter consists of helium, hydrogen, methane and ammonia.The surface of the Jupiter is mainly made of liquid hydrogen.

Slide 30

Jupiter is the first of the gas type planets. Below the surface, increasing pressure changes this liquid this liquid hydrogen to solid state.Jupiter appears to be the brightest object in the night sky. Jupiter’s bright appearance is due to the fact that is it has a thick, cloudy atmosphere which reflects most of the sunlight falling on it.Jupiter is a very cold planet, its surface temperature being,-180°c. Jupiter has 28 satellites .It has also some faint rings around it.
