Answers
Answer:
A. The Moon is Earth's only natural satellite. At about one-quarter the diameter of Earth, it is the largest natural satellite in the Solar System relative to the size of a major planet, the fifth largest satellite in the Solar System overall, and is larger than any known dwarf planet
B. The time interval between a full moon and the next repetition of the same phase, a synodic month, averages about 29.53 days. Therefore, in those lunar calendars in which each month begins on the day of the new moon, the full moon falls on either the 14th or 15th day of the lunar month.
C. Objects that do not have light of their own but they reflect the light of luminous objects that fall on them to our eyes are known as non-luminous objects. ... Moon doesn't give off light of its own, that's why the moon is considered a non-luminous body.
D. The moon's revolution around the earth takes about 27.3 days - sometimes called the lunar month. Interestingly, it also rotates on its axis in roughly the same period - 27 days. The result is that we on earth see only one 'face' of the moon night-to-night and month-to-month.
