Study Notes
Misconceptions about Earth-Moon Distance
- Common perception underestimates the vast distance between Earth and Moon due to visual representations in media and education.
- Scale models often depict the Earth and Moon much closer than they are to simplify understanding, leading to misconceptions.
Earth-Moon Model Spacing
- When accurately modeled with correct spacing, the Earth and Moon are further apart than most people's initial predictions.
- Actual average distance is approximately 238,855 miles (384,400 kilometers).
Number of Moons Fitting into Earth
- Roughly 49 Moons could fit inside the volume of one Earth.
- Earth's volume is about 1 trillion cubic kilometers, while the Moon's volume is around 21.9 billion cubic kilometers.
Size Comparison: Diameters of Earth and Moon
- Earth's diameter is about 7,917.5 miles (12,742 kilometers).
- Moon's diameter measures approximately 2,159 miles (3,474 kilometers).
- The Earth’s diameter is roughly 3.7 times larger than that of the Moon.
