To calculate the distance between Earth and the Moon, you can use the average distance value, known as the mean lunar distance. This value represents the average distance from the center of the Earth to the center of the Moon.
The mean lunar distance is approximately 384,400 kilometers (or 238,900 miles). Keep in mind that this value can vary due to the Moon's elliptical orbit around the Earth.
If you want a more precise calculation of the current distance, you can use astronomical data or online resources that provide real-time measurements of the Earth-Moon distance based on observations.
