If it's orbiting a primary more massive than itself, and its primary is not a star, then it's a moon.
Only the moon. And that hasn't happened since 1972.
An object that orbits the earth. for example the moon or the ISS or the telecommunication satellites that broadcast TV
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.
That depends on what you mean by "outer space". The moon is outside the Earth's atmosphere and therfore "in space" but it is orbiting the Earth and therfore hardly "outer".
The mass of the Moon, the mass of the object, and the distance to the center of the Moon.
The moon is the closest thing in outer space to the earth.
Titan is a moon that orbits Saturn, so it is in outer space.
Due to the fact that that was the way it was formed/collided with Earth (current theories sugges that the moon is a trapped object from another part of the solar system.)
Becuase so they can see the beauty of the whole outer space on the moon:)

The closest natural object to Earth is the moon.
