Earth ,the planet we call home, is part of a cosmic family called the solar system. It is one of the planets that revolve around a giant solar nuclear reactor that we call the Sun. The extreme heat and pressure on the Sun cause atoms of hydrogen to combine in a process called fusion, producing new atoms of helium and releasing tremendous amounts of energy. The Sun is the essential source of energy that makes life on Earth possible. It also provides us with light and warmth. Time on Earth is defined by our relationship to the Sun. It takes Earth, following a path called an orbit, approximately 365 days-one year-to make one full revolution around the Sun. As Earth makes its way around the Sun, it also turns on its axis, an imaginary line that passes between the poles. This motion, called rotation, occurs once every 24 hours and results in day and night.This is the Documentary Earth from Space. [caption id="attachment_847" align="alignnone" width="300"] ...

Mars, the fourth planet has a diameter of 6,794 kilometers and it orbits at a distance of 228 million kilometers from the Sun. The surface gravity on Mars is 0.38 of the Earth gravity and the planet is about one-tenth the size of the Earth. Mars moves at a speed of 4 kilometers per second and takes about 780 days to complete one revolution around the Sun.One rotation on its own axis is completed in about 24 hours and 37 minutes.It has two moons called phobos which is 23 kilometer in diameter and demos which is 13 kilometer in diameter.Since it is relatively closer to the Sun as compared to the other outer planets,the surface temperature ranges from -9 degree to 23 degree centigrade.In the earlier centuries the astronomers believed that the Mars was very much like Earth. Mariner VIII The first photographs of Mars taken by the Mariner IV spacecraft in the year 1965, subsequently Mariner VIII took some in the year 1971.As a result of these pictures it was discovered that the sur...
