What is a parsec?
A parsec is about 3.26 light years, or roughly 30.9 trillion kilometers. The name is short for "parallax second," because it comes from a measuring trick: a star one parsec away appears to shift by one arcsecond as the Earth moves across its orbit.
Professional astronomers usually prefer parsecs to light years, and they scale it up for bigger jobs — kiloparsecs for distances inside a galaxy and megaparsecs for the gaps between galaxies.
In writing, the parsec is usually shortened to "pc". One parsec is 3.085678e+16 meters, and that ratio is what every figure on this page is built from.
