gravity.
The force of a large body (the sun) causes the smaller body (Earth) to be drawn toward the large body. However, other bodies (other stars) and collections of bodies (solar systems and galaxies) act in the same way but to a lesser degree on the same small body (Earth). This creates a sort of equilibrium that carries things to orbit.
Add all of this together and you get an orbit, which is usually (if not always) elliptical (squashed circle). gravity also causes the sun to have its own orbit. All of these gravitational forces cause the orbit to diminish: Earth will eventually crash into the sun (supposing it stays lit that long) and Pluto will eventually fly away into space.
The force of gravity causes the moon to orbit the Earth, and the Earth to orbit the sun.
Gravity is the force that connects the solar system to the sun.
The mutual gravitational force between the satellite and the 'central' body.
GRAVITY!A2. Centripetal force. The velocity of the satellite around the earth causes centripetal, force which balances with the gravity, holding it in a circular orbit around the earth.
There are TWO forces that keeps objects in orbit; gravity and inertia. Everything is in motion. The force of inertia, the momentum that an object has BECAUSE it is moving, KEEPS the object moving - at a constant speed and in the same direction. But if inertia alone ruled, all of the planets would fly out away from the Sun. Another force must tie things together, and that is gravity. Gravity ties every mass to every other mass, pulling them together with a force that is proportional to their masses - but which decreases proportionally to the SQUARE of the distance between them.
the answer is........ gravity
The gravitational force.
Its a centripetal force, whose origin/source is gravitation.
gravity im pretty sure
Gravitational pull
it is a force called gravity.
The force of gravity causes the moon to orbit the Earth, and the Earth to orbit the sun.
Gravity is the force that connects the solar system to the sun.
The gravitational force between planets supplies the centripetal force that causes them to orbit each other.
The mutual gravitational force between the satellite and the 'central' body.
There is not a lot of gravity in space, but there is enought to keep the planets in orbit around the Sun.
Orbits are caused by the force of gravity combined with the speed of the object in the orbit. Saturn's rings consist of millions of small rocks in orbit round Saturn.
