The sun is a huge mass, 109 times bigger than the Earth. A mass this large has it's own gravitational pull, just as Earth does. The sun pulls all the planets into line so that they can get proper sunlight and life forms on them will not die. so, the cause of the orbiting of the planets is the suns gravitational pull.
They are held in place by the gravitational force of the sun.
Gravity causes objects, like planets, to orbit the Sun.
It was Isaac Newton who figured out that the force of gravity keeps planets in orbit around the sun.
Extra solar (or Exo) planets are planets that do not orbit the Sun. Planets in our solar system orbit the Sun.
Extra solar (or Exo) planets are planets that do not orbit the Sun. Planets in our solar system 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.

A planets gravitational pull is the force it exerts on other objects. The planets orbit is the path it takes due to gravity. Basically gravity causes the orbit.
Planets are kept in their orbit by the suns gravity, yet their momentum keeps them from falling into the sun. (Thank goodness!) Planets orbit in the direction their star rotates, so in our solar system, all planets orbit in the direction of the star.
The force keeping planets in orbit is gravity from another, larger planet or mass. The larger the planet, the greater the gravitational force it will have. To give an example, the sun in our solar system keeps earth and all the other planets in our solar system in orbit because it has the greatest mass, meaning it also has the greatest gravitational force.
Planets orbit around the Sun because of the Sun's gravitational force, it makes the planets move by its gravitational force.
Not all the planets orbit the sun - other stars have planets too. But all the planets in our solar system, which is the system of our sun, revolve around the sun; otherwise they would be in other solar systems. All the planets we can see with our naked eye orbit the sun, since the planets orbiting the sun are the only ones close enough to earth to see without a telescope.

it uses its force to make the planets orbit the sun.
