Description

It is the point in the Earth’s orbit when it is farthest from the sun (152.5 million km).

Example or term where used

When the earth is closest to the sun (perihelion), around 3rd January each year, tidal ranges are also much greater, with unusually high and unusually low tides. When the earth is farthest from the sun (aphelion),around 4th July each year, tidal ranges are much less than average. The time between the high tide and low tide, when the water level is falling, is called the ebb. The time between the low tide and high tide,when the tide is rising, is called the flow or flood.
