The Earth
is at its furthest point in its orbit around the Sun on July 4. At this point,
the Earth will be approximately 9.45 million miles or 15.21 million kilometers
from the Sun. The distance at this location will be 1.67% greater than the
average distance between the Sun and the Earth.
(The average distance between the Earth and the Sun is called an astronomical
unit and is equal to 9.29 million miles or 14.96 million kilometers.)
On a hot summer day it may be hard to imagine
the Earth being so far from the Sun, but seasonal temperature
changes are not caused by our distance from the Sun, but by the tilt of the Earth
on its axis in different directions. The tilted angle affects whether the sun's
rays will hit the Earth at a low angle or if they will hit the Earth directly.
Earth
will be at its closest orbit around the Sun on January 4, 2023, a mean distance
of 9.14 million miles (14.71 million kilometers). The earth's orbit is not
completely circular, due to which we have to face the conditions of aphelion
and perihelion. The degree to which a planet deviates from its full circle is
called eccentricity. Of all the planets in our solar
system, the orbit of Venus
is the closest to a spherical shape.
