The moon does not shine on its own, but it instead reflects light from the sun. However, it only reflects a small fraction of light, so humans don't see the moon as brightly they do the sun. This makes it safe to look at it without requiring eye protection.Know More
The moon revolves around Earth once per month and follows an elliptical orbit. Therefore, its distance and orientation vary, which is why the moon sometimes looks larger than other times. The same side of the moon is always facing the Earth because its rotation period matches its orbit around Earth.
Humans only see half of the moon from Earth at any given point during the month. Depending on where it is in relation to the sun, it looks different to observers. For example, the new moon occurs when the moon is between the sun and Earth, so humans see no reflected sunlight. Gradually, the moon begins to appear as a crescent, as a semicircle and as the full moon when sunlight reflects fully off the part visible from Earth. The full moon gradually wanes until the new moon is in the sky again at the start of the next lunar cycle.Learn more about Our Moon
Moon phases are caused by the motions of the Earth and moon as they relate to the sun. Phases occur as the Earth-facing side of the moon changes over the course of 29.5 days when the moon revolves around the planet. When the angle of sunlight reflecting off the moon changes, humans observe different lighting levels from the moon.Full Answer >
Crescent moons happen when Earth, the sun and moon are positioned in a way that only shows a portion of the reflected light on the moon. The result is a crescent-shaped light pattern.Full Answer >
The moon appears to shine because its surface reflects sunlight. Light from the sun travels through space to reach the Earth-moon system just over eight minutes after it is emitted. Some of this light falls on the surface of the moon where, according to Universe Today, 12 percent of it is reflected back into space.Full Answer >
The moon doesn't produce its own light, but it does reflect enough of the sun's light to cast a glow onto the Earth. The moon reflects so much light that it can even be seen during the day, during certain months.Full Answer >
