Objects on Earth are pulled by Earth's gravity more strongly than by the sun's gravity. Which of the following BEST explains this difference in gravitational force?

Objects on Earth are much closer to Earth than to the sun

Objects on Earth are touching Earth, but they are not touching the sun

The sun has more mass than Earth, so it pulls with less force than Earth does

The sun loses energy in the form of light and heat, so it pulls with less force than Earth
