Th earth and the moon are kept in orbit by gravity and mass. true or false

True

Explanation:

" Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun" .

Anything that has mass also has gravity. Objects with more mass have more gravity.Earth's gravity comes from all its mass.

Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth.

Hence, the statement " The Earth and the moon are kept in orbit by gravity and mass"  is TRUE.
