-The Earth has one moon in which we use as a natural satellite

On Earth we have four seasons they are caused by earth's axis. The four seasons are summer, winter, fall, and spring. Rotation is the spinning of Earth on its axis but while on Earth you can not feel the spinning motion. Revolution is the period of time it takes Earth to orbit the sun. Our energy comes from nuclear fission or the sun. You may have noticed that planets generally come in a circular shape and this is why, it has sufficient mass for its self-gravity to overcome rigid body forces so that is assumes a nearly round shape. Earth has light years. light years is the amount of time it takes light to travel in one year. And that is 186,000 miles per second. The force that is responsible for our galaxy is gravity. So now that you have read a few things on Earth you will have all the details to plan your perfect vacation on Earth.
