The gravitational pull of the sun keeps the planets in orbits...

planets are in orbit because of the suns gravitational field chupa naman diyan Planets are kept in their orbits by gravitational forces.
It was Nicholas Copernicus. who discovered that the sun keeps the planets one Their orbit.
Our planets are kept in their orbits around our star by the force of gravity.With all due respect, I should be surprised if the principle were not the samewhere you come from.
The planets are kept in their elliptical orbits around the Sun primarily due to the gravitational force exerted by the Sun. This gravitational pull acts as a centripetal force, continually drawing the planets toward the Sun while their inertia causes them to move forward in their orbits. According to Kepler's laws of planetary motion, the combination of this gravitational attraction and the planets' velocity results in elliptical orbits rather than circular ones.
The planets revolve in elliptical orbits. The inner planets have orbits 230 million km or less from the Sun. The outer planets have orbits 775 million km or greater.
Gravity from the Sun holds the planets in their orbits.
All the planets have orbits so four cannot be picked out.
Asteroids orbit the sun. Moons orbit planets and planets orbit the sun. So you could say the moons orbit the sun. However, moons are kept in their orbits by the gravity of their planet and planets are kept in orbit by the gravity of the sun. So in that sense, moons do not orbit the sun.
This question is nonsense. There is no need to "keep" the moon and planets in their orbits; the laws of physics ensure they stay there. The "conditions"... well, look around you. They're in their orbits now, so the current "conditions" must be the ones which apply when they are.
