Origins & Early Life

The Moon is the only natural satellite of Earth. It orbits Earth in an elliptical path, at a distance that varies over the year, averaging around 378,000 kilometers (235,000 mi). It completes an orbit (lunar month) in relation to Earth and the Sun (synodically) every 29.5 days.

Career & Major Achievements

The Moon and Earth are bound by gravitational attraction, which is stronger on the sides facing each other. The resulting tidal forces are the main driver of Earth's tides, and have pulled the Moon to always face Earth with the same near side. This tidal locking effectively synchronizes the Moon's rotation period (lunar day) to its orbital period (lunar month).

Enduring Legacy & Impact

In geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.2% that of the Earth, and its diameter is 3,474 km (2,159 mi), roughly one-quarter of Earth's (about as wide as the contiguous United States). Within the Solar System, it is larger and more massive than any known dwarf planet, and the fifth-largest and fifth–most massive moon, as well as the largest and most massive in relation to its parent planet.

Notable Quotes by Moon

“The Moon is prominently featured in Vincent van Gogh's 1889 painting The Starry Night.” (1889)

Historical Fact-Check Quiz: Moon

True or False: “The Moon's orbit is perfectly circular, maintaining a constant distance from Earth throughout the year.”

Answer (FALSE ❌): The Moon's orbit is elliptical, meaning its distance from Earth varies significantly over the course of the lunar year, averaging around 378,000 kilometers.
