That's why the group decided to try to save Earth.

　　The plan has one or two worrying aspects, though. For a start，space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation in orbit could fire it straight at Earth—with deadly consequences.

　　There is also the question of the Moon. As the current issue of Scientific American points out, if Earth was pushed out of its current position，it is most likely that the Moon would be stripped away from Earth. This would greatly change our planet's climate.

　　文章大意：本文是科普性文章，介绍了科学家们的一个关于移动地球的设想。
