The sun exerts the strongest gravitational pull on earth due to its massive size.
The gravitational pull of an object on earth is directly proportional to the mass of the object and inversely proportional to the square of distance of separation, according to Newton's law of universal gravitation.
[tex]F = \frac{Gm_1 m_2}{R^2}[/tex]
The mass of the sun is the largest among the given options. This enables the sun exert a very great gravitational pull on every planet that make up the solar system.
Thus, we can conclude that the sun exerts the strongest gravitational pull on earth due to its massive size.
