*Aphelian: July 4 is the Aphelian. On this day the Earth is most farthest from the Sun.

*Perihelion:  January, 3 is the Perihelion. On this day the Earth is most nearest to the Sun.

*Astronomical  Unit : 1 AU = 149,597,870 km. This is the approximate mean distance between Sun and Earth. So the mean distance is slightly varied.

*Summer Solstice: June, 21 is the longest day. On this day Sun is most far away from Earth’s Equator.

*Winter Solstice: December 22 is the shortest day. On this day Sun is most nearest to Earth’s Equator.

*Geoid:  The Earth is not a perfect sphere in shape. The earth like shape is called as Geoid.
