Detailed explanation-1: -As the Earth rotates, it rotates/revolves/moves around the Sun. This is considered the orbit of Earth’s journey around the Sun. This takes one year to orbit the Earth, or 3651/4 days. As the Earth orbits/rotates/revolves around the Sun, the Moon orbits the Earth.
Detailed explanation-2: -Earth orbits the sun once a year and rotates on its axis once a day. The Earth’s orbit makes a circle around the sun. At the same time the Earth orbits around the sun, it also spins.
Detailed explanation-3: -The Earth and the Moon rotate and revolve counterclockwise. The period of rotation and revolution for the Moon is the same, hence it presents the same face to us on Earth. The lunar “farside” has only been photographed and studied recently after space travel became a reality. The synodic month is 29.5 days.
Detailed explanation-4: -The rotation of the Earth on its axis causes day and night. As the Earth rotates, only one-half of the Earth faces the sun at any given time. The half facing the sun is light (day) and the half facing away from the sun is dark (night). The animation below shows the Earth’s rotation.
