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"] ...

By NED POTTER Related Content New Planet Found , Smaller Than … Thirty-three light-years away, in the constellation Leo the lion, astronomers say they have found a world considerably smaller than Earth , orbiting a dim red-dwarf star. That's something to think about. While scientists have confirmed the existence of more than 700 so-called exoplanets since 1995, most of them have been giant -- many considerably larger than Jupiter . This new world, say the researchers who found it, may be only 5,200 miles across, about two thirds as large as Earth. "People have been picking at the low-hanging fruit, since Jupiter-sized planets are easier to see," said Kevin Stevenson, the young researcher at the University of Central Florida who led the team making the find. "Now we're really pushing the limits of what our telescopes can find." The newly found world is, for now, called UCF-1.01, and Stevenson and his colleagues found it with NASA's Spitze...
