The gravitational force of the Sun is powerful enough to hold Earth in orbit even though Earth is an average of 150 million kilometers away. Which statement best describes why objects with much less mass than Earth are not pulled off the surface of Earth toward the Sun?

• Objects on Earth are influenced more by the gravity of Earth than by the gravity of the Sun.

• Objects on Earth are held by the gravity of the Moon.

• Objects on Earth have too little mass on which to pull.

• Objects on Earth are orbiting the Sun too quickly.
