SOLAR SYSTEM

Detailed explanation-1: -Question: The length of a lunar month is roughly 28 days. If the moon were located farther from the Earth than it presently is, the lunar month would beChoose one answer. a. more than 28 days.

Detailed explanation-2: -The synodic month is the time from one new Moon to the next. It ranges from 29.27 days to 29.84 days with a mean of 29.53 days. 12×29.5 = 354, so a lunar year consisting of 12 lunar months is about 11 days short of a solar year. 19 solar years is almost exactly 235 lunar months.

Detailed explanation-3: -Cycle of lunar phases takes 29.5 days this is the SYNODIC PERIOD. Why is this longer than the SIDERIAL PERIOD which was 27.3 days? very simple: this is because the moon returns to the same place on the sky once every siderial period, but the sun is also moving on the sky.

Detailed explanation-4: -Does the Moon orbit Earth? Yes. The Moon takes about one month to orbit Earth (27.3 days to complete a revolution, but 29.5 days to change from New Moon to New Moon). As the Moon completes each 27.3-day orbit around Earth, both Earth and the Moon are moving around the Sun.

Detailed explanation-5: -Lunar calendars are based on the phases of the moon as seen from the earth. One lunar month is the time of one lunar cycle which is nearly 29.5 days.
