How long, in Earth days, is the Moon's orbital period that matches its rotation period?
Answer
Approximately 27.3 Earth days
The defining characteristic of synchronous rotation is the perfect synchronization between the time the Moon takes to complete one rotation on its axis and the time it takes to complete one orbit around the Earth. The text specifies that this period is approximately 27.3 Earth days. This means that for every 27.3 days that pass, the Moon travels its full orbital path while simultaneously spinning exactly once on its axis, resulting in the constant presentation of the near side to our planet.
