Did you know that the moon is the natural satellite of the Earth? A moon is a planetary-mass object that forms a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term. In the year 1969, Neil Armstrong was the first to land on the moon.
The phase of the moon in which its whole disc is illuminated is known as the full moon day. This happens only when the moon is opposite the sun. A new moon occurs when the moon is on the same side of Earth as the sun. A new moon can be seen during a solar eclipse.
Various phases of the moon are:
- Full moon
- New moon
- Waning crescent moon
- First-quarter moon
- Waning gibbous moon
- Last quarter moon
- Waxing crescent moon
- Waxing gibbous moon
The moon does not have its own light. It can only reflect light from the sun. Only the side of the moon that faces the sun can reflect this light and appear bright. The moon’s dark side refers to the moon’s far side, and it is not dark.
The moon’s distance from the Earth is about 240,000 miles. The water present on the moon is known as lunar water.
