When it an object in space in moving it will keep moving at the same speed with the property of inertia. Then moon is an object that has inertia. Gravity keeps the moon from going off into outer space but inertia keeps the moon from crashing into the moon. Gravity and inertia have to be balanced in order for an object to remain in orbit.

No. They orbit Earth; and the reason they orbit is because of gravity.
the suns gravity keeps the planets in orbit
Gravity plays the central role; without gravity, there would be no such thing as an orbit.
Any moon is held in orbit by gravity, just as the planets are held in orbit around the sun by gravity.
Friction has 100% nothing to do this the Earths orbit, its gravity and inertia.

There is not a lot of gravity in space, but there is enought to keep the planets in orbit around the Sun.
Gravity.
gravity and inertia combine to keep earth in orbit because the suns gravity keeps the earth in orbit and the inertia keeps the earth from going in a straight line.
There certainly is gravity outside the atmosphere. For example, it is gravity that keeps the Moon in orbit around the Earth, and the Earth in orbit around the Sun.
