“The point on its orbit where it is most distant from Earth is known as apogee, and the point where it is closest is known as perigee. Three or four times a year the perigee coincides with a full Moon, which astrologers in the first part of the twenty-first century c.e. dubbed a “supermoon.” The closer Moon yields exceptionally high and low tides. The more distant, apogee Moon—call it a micromoon—is slightly smaller in the night sky and has a weaker pull. But even a faraway Moon exerts a powerful influence over Earth.”
