According to newton's law of universal gravitation, the sun would have gravity than earth because it's more

1. more / less

2. massive / distant

1. more
2. massive

". . . a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them."

Simply little things gravitate to big things, if both of them have enough proportional mass.
