At the center of the Earth, scientists think there is a ...
... because it has mass. Space is a void and therefore has no mass, so it cannot have gravity. As long has Earth has mass, it will continue to have gravity. If Earth were to lose its mass, it would cease to exist, so there's really no way that Earth can ever lose its ...

For low Earth orbit (about 200 miles above the Earth) it takes about 90 ... that means it takes them a longer time to orbit around the Earth. There is one special orbit where it takes a full day to orbit around the Earth. So a satellite in this orbit travels around the planet at the same rate that the planet is spinning To return to Earth, it ...
Space does not move—any movements that human beings or spacecraft make in space must be judged relative to some other object like the Earth or the Shuttle. For example, the Space Shuttle travels in an orbit that requires it to have a speed of 17,500 miles per hour (mph). If an astronaut steps out of the Shuttle to perform some activities in space, he ...
