Gravity and inertia.
The force of gravity between the moon and the planet is what keeps the moon in orbit around the planet. This gravitational force prevents the moon from floating away into space and keeps it in a stable orbit.
No. The outer planets do not have solid surfaces. Those planets are made of gases held together by gravity.
The inner planets are closer together than the outer planets are.
The inner planets are closer together than the outer ones.
No. The reverse is true.
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.
The inner planets are closer together than the outer ones.
The inner planets (Mercury, Venus, Earth, and Mars) are closer together compared to the outer planets (Jupiter, Saturn, Uranus, Neptune) in our solar system. The inner planets have shorter average distances between each other, resulting in a more compact grouping compared to the outer planets.
Their characteristics are similar.
The force of Gravity.
All of the outer planets are made up of hydeogen and helium and all have rings that surround them and are generally all bigger than the inner planets
because of gravitational force of the earth is more in inner planet
