Amazing Facts About a Planet.

It is believed that our planet is more than 4.5 billion years old and recent evidence actually shows that earth was formed much earlier and that our planet stores more than two million cubic miles of fresh water. Earth is the only planet on which water can exist in liquid form on the surface. The ozone molecules and the average thickness of the layer is believed to be 50 km. We know that our planet rotates but is more flexible than we might imagine as it bulges at the midsection creating a pumpkin shape. The bulge was lessening for centuries but now it is said to be growing and in turn the rotation is slowing down which would lengthen the days. Earth has one moon but ‘3753 Cruithne’ which is 5 km across is sometimes called Earth’s second moon. It is estimated that there are some 5 to 30 million different species on earth and about 2 million species have actually been identified and described. When astronauts first went into the space, they looked back at the earth with human eyes for the first time and called it as a Blue Planet. Yuri Gagarin, who was the first man to travel into space, said that she is so beautiful and I could not help but love and cherish her.
We live on a planet of extremes. It is not only a beautiful sphere but it is a wild planet with deadly volcanoes and killer earthquakes. The windiest/coldest/driest and hottest places, the deepest places in the ocean and tallest peaks. Are we not living in an amazing planet?
