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 It has largely been superseded by other units like the parsec and light-year.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 Megaparsec

The parsec (symbol pc) is a unit of length used in astronomy. It stands for "parallax of one arc second", and is approximately 19,131,554,073,600 (19 trillion) miles.
