About These Units
About Astronomical Unit
An Astronomical Unit is approximately the mean distance between the Earth and the Sun. It is a derived constant and used to indicate distances within the solar system. Its formal definition is the radius of an unperturbed circular orbit a massless body would revolve about the sun in 2*(pi)/k days (i.e., 365.2568983.... days), where k is defined as the Gaussian constant exactly equal to 0.01720209895. Since an AU is based on radius of a circular orbit, one AU is actually slightly less than the average distance between the Earth and the Sun (approximately 150 million km or 93 million miles).
About Kilometer
The kilometer is one of the most common metric units of length or distance. One kilometer equals exactly 1000 meters (metres), about 0.62137119 mile, 1093.6133 yards, or 3280.8399 feet.
