The gravitational pull of the planet that the moon orbits keeps it from leaving orbit. But the speed of its motion around the planet allows it to avoid being pulled in.
Some orbits change over time, as the effects of gravity by other moons or planets can cause them to shift. In some cases, this results in moons being thrown out of their stable orbits. In other cases, a wandering asteroid may be captured by a planet's gravity and assume an orbit with the other moons.

Is there a moon that doesn't orbit a planet?
A moon must orbit a planet, or it isn't a moon, it's a planet.
Which planet does the moon Ariel orbit?
Ariel is a moon of the planet Uranus.
How can you tell someting is a planet not a moon?
The planet will orbit the sun, while moons orbit the planet.
How can you tell something is a planet and not a moon?
A planet is in direct orbit around a central star, while a moon is in orbit around a large body (a planet) rather than in a direct orbit around a star. The moon orbits the planet, while the planet orbits the sun.
How do the orbit of planets differ from the orbit of moons?
A planet orbits a star. A moon orbits a planet or dwarf planet.
What keeps a moon in orbit around a planet?
gravity :)
What force keeps a planet or moon in its orbit?
GravityCentripetal Force.
What keeps a satellite in orbit around a planet and why?
the forse of gravity keeps it floating in space like the moon orbits our planet
Is there a moon that doesn't orbit a planet?
A moon must orbit a planet, or it isn't a moon, it's a planet.
Which planet does not directly orbit moon?
Every planet does not directly orbit the Moon.
How do planets stay in orbit around the moon?
the moon orbits around the planet, not the other way around; gravity keeps it orbiting
What keeps the moon in its orbit around the moon?
The balance between the inertia of the Moon and the gravitational pull keeps the moon in orbit with Earth.
What is the force that keeps planet in orbit?
the suns gravity keeps the planets in orbit
Does Venus orbit a planet?
No, Venus does not orbit a planet. It orbits a star, which is our Sun. It can not orbit a planet , if it did it would be a moon
What does a moon have to have?
A Planet to orbit.
Which planet does the moon Ariel orbit?
Ariel is a moon of the planet Uranus.
How is a orbit made?
A planet or moon orbits the Sun (or a planet) and then makes an orbit
