Question

how long is the lunar phase cycle? * 2 points 14 days 27.3 days 29.5 days 365 days

Explanation:

The lunar phase cycle, also known as the synodic month, is the time it takes for the Moon to cycle through all of its phases (new moon to new moon). This period is approximately 29.5 days. The 27.3 - day period is the sidereal month (the time it takes the Moon to orbit Earth relative to the fixed stars). 14 days is roughly half of the lunar phase cycle (from new moon to full moon or vice - versa). 365 days is approximately the length of a year (Earth's orbit around the Sun).

Answer:

29.5 days
