Earth and the moon.
Mutual gravitational attraction between the Earth and moon keep the moon in orbit. Conservation of angular momentum may also be considered to play a role.
Mutual gravitational forces between the Earth and Moon are.
The mutual force of gravitational attraction between any two masses is proportional; tothe square of the distance between their centers.When an object is moved twice as far from the planet's center, the force between themdecreases to 1/22 = 1/4 of its original magnitude.

Sort of...any body of mass exerts its own gravitational pull (the Suns gravitational pull keeps Earth in its orbit, while the Earth's gravitational pull keeps the Moon in its orbit - and us on the surface). Even Humans, dogs, turtles and snails exert some gravitational influence on their surroundings - but in such a low strength as to not have any noticable impact on the immediate surroundings.
Mutual force of gravitational attraction.
That's the mutual gravitational force of attraction between the satellite and the central body that it's orbiting.
The mutual gravitational attraction between you and the earth.
The mutual force of gravitational attraction between the sun and the earth.
-- distance -- equal mutual forces of gravitational attraction
The mutual gravitational force of attraction between you and the sun decreases as you move farther from the sun. Just the same as the mutual gravitational force of attraction between you and the earth, or any other body, decreases as you move farther from the other body.
It is held in its orbit by the mutual gravitational attraction between the earth and the moon.
That's the mutual gravitational attraction between the sun and the earth.
They are held there by their mutual gravitational attraction.
A pair of equal mutual gravitational forces of attraction along the line between their centers does.
The mutual gravitational attraction between the satellite's mass and the earth's mass. Short answer: The force of gravity.
That's the mutual gravitational force of attraction between the satellite and the central body that it's orbiting.
