the primitive sun was more like a rotating disc and because of the centrifugal force a piece of the sun was thrown out,but with a velocity parallel to the solar disc. So it becomes a satellite to the sun. The force that makes the planet rotate around the sun is the gravitational force which is also called the centripetal force which in turn is balanced by the centrifugal force. The elements in a planet can be different from those of the sun because of nuclear synthesis that takes place during the planet's life.
an orbit is the circular movement of a planet going round the sun, or a moon going round a planet. Gravitaional force is what creates the orbit.
You can consider a dwarf planet to be a special case from an asteroid - one that has achieved hydrostatic equilibrium, which basically means that it has enough gravity to force it into a round shape.
Sun's Gravitational force.
Gravity..
Gravity causes a spinning planet to stay more or less round, assuming it became that way when it was still molten or is a gas planet. However, centrifugal force can oppose the gravitational force, causing a planet to bulge out at its equator and flatten slightly at the poles.
Orbits help a planet move because of gravitational pull which makes the planet orbit round and round. The planets orbit around the son and the moon orbits around earth. Hope this helps!
round?
The earth's gravity field makes everything push into the earth like a bubble arround the planet. This makes it seem like the earth is flat.
It spins on its axis and the centrifugal force makes the part at the equator bulge out slightly.
beacause every planet is round
The orbit of each planet it the path it takes as it rotates round the Sun under the influence of the force of gravity. Every planet has a separate orbit and the orbits all follow Kepler's three laws of planetary motion.
It's an optical illusion. The wheels on my mondeo turn the planet to where I need to get to whilst I stay in the same place in space.
