What is Parsec?
Parsec is a length unit used to express distance, size or travel range in practical measurement work.
Short history of Parsec
Parsec is short for 'parallax of one arcsecond', a term coined by astronomer Herbert Hall Turner in 1913. It is the distance at which one astronomical unit spans one arcsecond, about 3.26 light-years.
