Causes the planets to orbit the sun,
Causes the moon and artificial satellites to orbit the Earth,
Causes comets to orbit the sun.
- Planets further away from the sun travel more slowly because the further the distance away, the smaller the gravitational pull
- There is gravitational pull between both masses, the larger the masses the stronger the pull, every object is surrounded by it’s own gravitational field which exerts an attractive force on all objects
- As the earth is greater than the moon, it attracts the moon and orbits the Earth
Reminder thrat planets do not emit light, they just reflect the sun’s light.
