| A beautiful blue and white ball when seen from space. You’ve lived on this planet all your life, but how much do you really know about the ground underneath your feet? Earth..The planet formed 4.54 billion years ago and life appeared on its surface within a billion years, it is also referred to as Terra home of millions of species. The Earth is expected to continue supporting life for another 1.5 billion years after which the rising luminosity of the Sun will eliminate the biosphere. About 71% of the surface is covered with water, liquid necessary for all known life. Earth is the 3rd planet from the Sun at a distance of about 150 million kilometers (93.2 million miles). It takes 365.256 days for the Earth to travel around the Sun and 23.9345 hours for the Earth rotate a complete revolution. It has a diameter of 12,756 kilometers (7,973 miles), only a few hundred kilometers larger than that of Venus. Our atmosphere is composed of 78 percent nitrogen, 21 percent oxygen and 1 percent other constituents. As you’re probably aware, Earth has 1 moon. But did you know there are 2 additional asteroids locked into a co- orbital orbits with Earth? They`re called: 3753 Cruithne and 2002 AA29. Earth is the only planet known to have life but if there’s life on other planets, we hope find it. |
