Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass.

Can we create gravitational force?
Artificial gravity can be created using a centripetal force. A centripetal force directed towards the center of the turn is required for any object to move in a circular path. In the context of a rotating space station it is the normal force provided by the spacecraft's hull that acts as centripetal force.
How do you create gravitational energy?
What causes gravitational energy? Systems can increase gravitational energy as mass moves away from the centre of the Earth or other objects that are large enough to produce significant amounts of gravity (like our Sun, the planets and stars).
Can spinning create artificial gravity?
Dave: In space, it is possible to create "artificial gravity" by spinning your spacecraft or space station. When the station spins, centrifugal force acts to pull the inhabitants to the outside. This process could be used to simulate gravity.
Does Earth’s rotation cause gravity?
Gravitational acceleration contributes to the total gravity acceleration, but other factors, such as the rotation of Earth, also contribute, and, therefore, affect the weight of the object. Gravity does not normally include the gravitational pull of the Moon and Sun, which are accounted for in terms of tidal effects.
What is an example of a gravitational force?
Some examples of the force of gravity include: The force that holds the gases in the sun. The force that causes a ball you throw in the air to come down again. The force that causes a car to coast downhill even when you aren't stepping on the gas.
Can gravity be created or destroyed?
No,you cannot destroy gravity(gravitational force). But you can escape from the pull of the earth towards its centre by travelling at the earth's escape velocity(11.2 km/s) or greater. Then you will be orbiting the earth. That's the most you can do.
How do black holes affect gravity?
Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity.
At what height does gravity stop?
It is a common misconception that astronauts in orbit are weightless because they have flown high enough to escape the Earth's gravity. In fact, at an altitude of 400 kilometres (250 mi), equivalent to a typical orbit of the ISS, gravity is still nearly 90% as strong as at the Earth's surface.
Would we still have gravity if the Earth stopped spinning?
If the Earth stopped spinning, you wouldn't suddenly be launched off into space. Gravity would still keep you firmly on the ground. There would be lots of changes, though. If Earth were to stop spinning but continue to orbit the sun, a "day" would last half a year, and so would the night.
