Understanding Moon Phases and Characteristics

The video tutorial from the Lighthouse Lab explores the moon's visibility, orbit, and phases. It explains that the moon is visible because it reflects sunlight and appears larger than stars due to its proximity to Earth. The moon's orbit around Earth takes about 27.3 days, and it rotates on its axis in the same period, keeping the same side facing Earth. The phases of the moon, such as waxing and waning, are caused by the varying amounts of sunlight reflected as the moon orbits Earth. The tutorial concludes with a visual representation of the moon's phases as seen from the southern hemisphere.

What is the primary reason we can see the Moon at night?

• It emits its own light.

• It reflects sunlight.

• It is larger than the Sun.
