Question

why does earth orbit the sun rather than any other body in the solar system? a) the mutual repulsions among all the planets hold earth in its orbit. b) the earth is closer to the sun than other bodies in the solar system. c) the sun is the most massive object; gravitational attraction is related to mass. d) the rotational motions of all the planets, including earth, cause them to remain in its orbit around the sun.

Answer 1

Answer: c) the sun is the most massive object; gravitational attraction is related to mass.

Explanation:

Gravitational pull exists between any two objects having mass.  

$F =\frac{GMm}{r^2}$

where symbols have their usual meaning.

All the planets including Earth revolve around the Sun because its the most massive object in the neighborhood and thus has high gravitational pull. This gravitational pull of Sun keeps the Earth in its orbit around it.  

Hence, the correct answer is earth orbit the sun rather than any other body in the solar system because c) the sun is the most massive object; gravitational attraction is related to mass.
