　　Move Earth—it’s no science fiction

　　Scientists have found an unusual way to prevent our planet from overheating：move it to a cooler spot.All you have to do is send a few comets in the direction of Earth，and its orbit will be changed.Our world will then be sent spinning into a safer，colder part of the solar system.

　　This idea for improving our climate comes from a group of US National Aeronautics and Space Administration(NASA) engineers and American astronomers.They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.

　　The plan put forward by Dr.Laughlin，and his colleagues Don Korycansky and Fred Adams，needs carefully directing a comet or asteroid so that it passes close by our planet and sends some its gravitational energy to Earth.

　　“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun，” Laughlin said.

　　Engineers would then direct their comet so that it passed close to Jupiter or Saturn.The comet would pick up energy from one of these giant planets.Later its orbit would bring it back to Earth，and the process would be repeated.
