The Red Planet

The ancient Romans named this planet after the name of god of war ‘Mars’ due to its reddish colour. The red planet may hold the key of future for the humanity. The journey of mars begin 4.5 billion years ago when a huge cloud of dust eventually formed a planet. Mars is the 4th planet from the mighty star sun and is the second smallest planet in the solar system. The radius of mars is approx 3400 km, and the entire surface area of this planet is equal to the combined surface area of all the continents of earth.

Mars have a volcano named Olympus which is the largest volcano in the entire solar system and it is 3 times the height of the Mount Everest, the height of Olympus in around 25 km. It is dense and has a rocky composition, the core is mostly made of iron, nickel and sulphur and the crust is rich in iron. The iron reacts with trace amount of oxygen & mars atmosphere which results in its reddish colour It is dry and cold and temperature may fall as low as -1420C.

But billion of years ago it was much warmer, had watery surfaces and river valleys which indicates that liquid water may be present over a period of time. Now water exists in the form of polar ice caps and scientist believe that life may have existed on the red planet and may exist again. Who knows that may be one day we will spend our summer vacation on the mars or maybe we live there permanently.
