The elliptical orbits of the moon around the Earth and the Earth around the sun have substantial effects on the Earth’s tides and the currents they produce. When the moon and Earth are positioned nearest to each other (perigee), the currents are stronger than average and are called “perigean currents.” When the moon and Earth are at their farthest distance from each other (apogee), the currents are weaker and are called “apogean currents.”
