Final answer:
The distance from the sun and the mass of the planet affect the sun's gravitational pull.
Step-by-step explanation:
The two factors that affect the sun's gravitational pull on a planet are the distance from the sun and the mass of the planet. The closer a planet is to the sun, the stronger the gravitational pull. Similarly, the greater the mass of the planet, the stronger its gravitational pull on the planet.
