What is a Moon Percentage?

A Moon Percentage refers to the amount of the moon's surface that is illuminated and visible from Earth at a particular time. This percentage can range from 0% (new moon) to 100% (full moon). The moon's phase, position in its orbit around the Earth, and the Earth's position in its orbit around the sun all contribute to the moon percentage.

Formula

The formula to calculate the moon percentage is:

\[ \text{MP} = \left(\frac{\text{DI}}{29.53}\right) \times 100 \]

Where:

Example Calculation

Let's assume the following values:

Using the formula:

\[ \text{MP} = \left(\frac{15}{29.53}\right) \times 100 \approx 50.8\% \]

The moon percentage is approximately 50.8%.
