Question

What keeps all planets, dwarf planets, asteroids, comets and other bodies bound to the solar system?

• A. Their shape
• B. Their colour
• C. Gravitational pull from the Sun
• D. Their size

Answer 1

The correct option is C Gravitational pull from the Sun

$\bullet$ All planets, dwarf planets, asteroids, comets and other bodies of our solar system revolve and hence have a tendency to move away from the Sun.
$\bullet$ The gravitational pull from the Sun keeps all the planets in their orbit.
