SOLAR SYSTEM

Detailed explanation-1: -The Moon gets its light from the Sun. In the same way that the Sun illuminates Earth, the Moon reflects the Sun’s light, making it appear bright in our sky.

Detailed explanation-2: -Like Earth, the Moon has a day side and a night side, which change as the Moon rotates. The Sun always illuminates half of the Moon while the other half remains dark, but how much we are able to see of that illuminated half changes as the Moon travels through its orbit.

Detailed explanation-3: -The full Earth illuminates the lunar landscape. And that is earthshine. It’s light from the nearly full Earth shining on the moon. So next time you see a crescent moon, expand your thinking to include the Earth under your feet.

Detailed explanation-4: -Moon does not emit its own light and therefore is a non-luminous object. Moon is visible only when it reflects light from the sun.

Detailed explanation-5: -The full moon is the lunar phase when the Moon appears fully illuminated from Earth’s perspective. This occurs when Earth is located between the Sun and the Moon (when the ecliptic longitudes of the Sun and Moon differ by 180°).
