What is the approximated distance that the earth
is approaching the sun each day, week, month, year
or other method of measurement used scientifically?
The earth is not approaching the Sun. The earth
moves around (orbits) the Sun and moves on a
slightly elliptical orbit. The mean distance
between Earth and Sun is 1.5x1011
meters or one Astronomical Unit. The speed of the
Earth around the Sun on this orbit is about 30
km/second. The Earth is closest to the Sun on Jan
3rd and furthest from the Sun on July 4th,
currently. The time of the year of perihelion and
aphelion varies as a slowly (geologic time)
function of time on.
