SOLAR SYSTEM

Detailed explanation-1: -The Moon takes about one month to orbit Earth (27.3 days to complete a revolution, but 29.5 days to change from New Moon to New Moon).

Detailed explanation-2: -Moon fact: The Moon’s phases repeat every 29.5 days, but it’s orbit around the Earth only takes 27. Why? In that time, as our Moon moves around Earth, the Earth also moves around the Sun. Our Moon must travel a little farther in its path to make up for the added distance and complete its phase cycle.

Detailed explanation-3: -The Moon takes 28 days to orbit Earth. As the Moon orbits the Earth, light from the Sun is reflected by the Moon’s surface. This allows us to see the Moon. When the Earth is directly between the Sun and the Moon, we see a full moon. This is because the side of the Moon reflecting sunlight is facing us.

Detailed explanation-4: -The moon orbits the Earth once every 27.322 days. It also takes approximately 27 days for the moon to rotate once on its axis. As a result, the moon does not seem to be spinning but appears to observers from Earth to be keeping almost perfectly still.

Detailed explanation-5: -This is because it takes the same amount of time to spin on its axis once as it does to orbit the Earth once. The gravity between the Earth and the Moon caused this special case of tidal locking (called synchronous rotation).

Detailed explanation-6: -The Moon is Earth’s only natural satellite (a celestial body that orbits a planet). It takes the Moon 27.3 days to make a complete orbit around the Earth, but because the Earth is moving around the sun at the same time, it takes the moon 29.5 days to go through its eight different ‘phases’ – a lunar month.
