About These Units
About Siriometer
The <b>siriometer</b> is an obsolete astronomical unit of length equal to one million astronomical units (AU), approximately 149.6 trillion kilometers. Named after the star Sirius, it was proposed for measuring extremely large distances in space, particularly for galactic astronomy. It has largely been superseded by other units like the parsec and light-year.
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).
