The gravitational force of the earth prevents the moon from flying off, which orbits Earth once every 27 days, reflecting the moonlight from the sun's light.
Earth and the moon are the astronomical bodies found in the solar system. Moon is the natural satellite of the planet Earth and lacks an atmosphere and is one-quarter of the earth in size.
The gravitational force present on earth keeps the moon in a proper position and the moon completes its orbits around the earth, approximately in 27 days.
The moon shines brightly and reflects the light from the sun as it lacks its own light. The full moon is the shiny and big-round phase of the moon.
Therefore, the correct blanks are gravitational force, 27 days, sun, and full moon phase.
