SOLAR SYSTEM

Detailed explanation-1: -Some nights, the Moon might look like a narrow crescent. Other nights, the Moon might look like a bright circle. And on other nights, you might not be able to see the Moon at all. The different shapes of the Moon that we see at different times of the month are called the Moon’s phases.

Detailed explanation-2: -As the Moon waxes (the amount of illuminated surface as seen from Earth increases), the lunar phases progress through new moon, crescent moon, first-quarter moon, gibbous moon, and full moon. The Moon then wanes as it passes through the gibbous moon, third-quarter moon, crescent moon, and back to new moon.

Detailed explanation-3: -A moon phase is the shape of moon’s sunlit portion as seen from Earth. There are a total of eight moon phases: new, waxing crescent, first quarter, waxing gibbous, full, waning gibbous, third quarter, and waning crescent.
