no, then inner solid planets are more dense than the outer gas planets
Gravity from the Sun holds the planets in their orbits.
there 9 planets one is moved
The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.
None of the planets pass out of our solar system. The orbits of the planets, irregular as they may be IS the solar system.
Gravity holds the planets in their orbit
All planets in our solar system have elliptical orbits.
It doesn't. All of the planets in our solar system orbits the sun.
Yes, none of the planets in our solar system have exactly circular orbits, though some are more eccentric than others.
All the planets have elliptical orbits but Uranus and Neptune have slightly different orbits than other planets on solar system.
orbits of the planets.
The planets and other objects in the solar system stay in their orbits due to the mutual gravitational attraction between each orbiting object and the Sun.
