Earth has a definite orbit within the soalr system. This orbit is mainy a result of the

• mass of the Sun.

• size of the Moon.

• pulling force of other planets.

• distance between other planets.

Jupiter revovles around the sun in a predictable pattern because

• Jupiter has a greater mass than other planets.

• the electromagnetic force from the Sun reaches Jupiter.

• the force of gravity between Jupiter and the Sun maintains the orbit.

• Jupiter has high winds that keep it moving at a constant rate.

The planets of the solar system revolves around the sun because the sun is

• made of hydrogen and helium.

• older than other objects in the solar system.

• the source of most heat and light energy.

• the strongest source of gravity in the solar system.
