All planets have gravity, and will attract other objects. The strength of the attraction is determined by the mass of the planet and the distance to the object.

Keeps objects orbiting a planet from flying off into space?
gravity
How does gravity keep the earth in orbit around the sun?
Sun's gravitational pull keeps the earth in an elliptical orbit around it.If there would be no gravitational pull of sun on earth than the earth would start moving in a straight line at an angle of 90 degree like a tangent to a circle.
What two factors combine to keep the planets in their orbits?
None do. If the forces on a planet were balanced, then it would take off in a straight line at constant speed, not remain in orbit. The only force acting on a planet is the gravitational one, that attracts the planet toward the sun. Fortunately, that's the only force required to keep the planet in orbit.
Why do objects weigh less on the moon than they do on the earth?
Gravity is strong here. It is the same reason we are held down on the planet
Does gravity pull objects down toward earth?
yes gravity pulls object toward the earth Here on Earth, the force of gravity does indeed pull objects down toward the Earth. But bear in mind that gravity is a universal force. On the planet Mars, for example, gravity pulls objects toward Mars. All objects in the universe have their own gravitational force, the strength of which depends upon how massive the object is. The sun is much heavier than the Earth, and the gravitational attraction of the sun is enormously greater than that of the Earth.
How do gravity and inertia keep the planet in orbit around the sun?
inertia keeps the planets moving and spinning , and gravity is a force that attracts all objects toward each other.
Does gravity come from the ocean?
Not only from the ocean. EVERY object in the Universe attracts EVERY OTHER OBJECT, through a force called gravity. So, the ocean attracts us, but so does every other part of planet Earth.
Is earth the only planet with gravity?
yes and no, planet earth is the only earth with gravity because there is only one earth, however planet earth is not the only planet with gravity or even the only object with gravity. every single planet and every star and even every comet or asteroid has gravity but its not just objects in space; everything is made of matter and all matter attracts other matter which is what causes gravity so the chair your sitting on, the computer in front of you, and even you have a small amount of gravity.
What is effects of gravity on different planets?
Exactly the same as its effects on Earth with which we are so familiar with. Every planet attracts objects on or near it toward its center, with a gravitational force that depends on the mass of the object, as well as on the mass and size of the planet.
Why neptune gravity pull people in?
Gravity is an attractive force that occurs between all objects with mass. The gravity of any planet will pull objects in.
What is the role of gravity as it relates to celestial bodies?
The celestial bodies attract one another through gravity. Among other things, gravity will:* Keep objects, such as planets, in orbits around other objects, such as stars. * Change orbits - e.g., one planet may influence the orbit of another planet. * Make objects such as stars and planets form in the first place.
How does the gravity of a planet vary with it's mass?
Objects have a gravitational pull proportional to their mass.
What determines gravity pull on a planet?
The force of gravity is determined by the masses of the objects and their distance apart.
How would you explain your weightlessness of objects in outer space?
Objects dont have weight, its the gravity of whatever planet its on and its own gravity. If you were in space there would be no gravity therefore no weight.
What are some examples of newtons second law in space?
They apply in space, just as they do on Earth. For example, if a force attracts a planet (most likely, a gravitational force), the planet will accelerate, i.e., its velocity will change.
What force holds a planet's atmosphere in place?
Gravity holds the atmosphere around the planet. Gravity is the force that attracts a body toward the center of the planet. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.
