WebMegaparsec. Just like the parsec (an abbreviation for Parallax of one arcsecond) and kiloparsec (equivalent to 1,000 parsecs, or KPC for short), the megaparsec (or MPC) is a measurement unit that is used in astronomy to measure the great, vast distance between galaxies in intergalactic space. It is said that one parsec is equal to about 3.3 light years. WebThe parsec (symbol pc) is a unit of length used in astronomy. It stands for " parallax of one arc second ". It is based on the method of trigonometric parallax, one of the most ancient and standard methods of determining stellar distances.
