The sun has the largest gravitational pull on other objects among Earth, the sun, and the Moon.
Here’s why:
1. **Mass**: The gravitational force an object exerts is directly related to its mass. The sun is vastly more massive than both the Earth and the Moon. The mass of the sun is about 333,000 times that of the Earth, while the Earth is about 81 times more massive than the Moon.
2. **Gravity and Distance**: While gravity also depends on distance, the sheer mass of the sun means that its gravitational influence dominates the solar system. Objects that are significantly farther away from the sun (like planets, comets, and asteroids) are still affected by its gravitational pull.
3. **Comparison to Earth and Moon**: The Earth's gravity is substantial and affects objects near its surface, but it is negligible compared to the sun's gravitational effect across the solar system. The Moon, while it does exert a gravitational force on objects (including Earth), is much less significant due to its lower mass.
In summary, the sun, being a star with immense mass, exerts the largest gravitational pull among the three celestial bodies.
