Parsec unit to meters Pc#
Reminder: a parsec (a parallax of one arc-second, or arcsec) is a natural distance unit (for astronomers at least) because the astronomical unit (the length of the semi-major axis of the Earth’s orbit around the Sun, sorta) and arcsec are everyday units (again, for astronomers at least). The table shows these units and gives their equivalent in m. 1 pc 3.0856775809623E+16 m / Convert parsec to meter. 1 Parsecs to Meters 3.08567782E+16: 70 Parsecs to Meters 2.159974474E+18: 2 Parsecs to Meters 6.17135564E+16: 80 Parsecs to Meters 2.468542256E+18: 3 Parsecs to Meters 9.25703346E+16: 90 Parsecs to Meters 2.777110038E+18: 4 Parsecs to Meters 1.234271128E+17: 100 Parsecs to Meters 3.08567782E+18: 5 Parsecs to Meters 1.
2) Being a contraction of PARallax SECond. I have read two different rephrasings of the definition of a parsec: 1) The distance one would have to be from two luminous objects seperated by one Astronomical Unit in order for them to appear one second of arc apart. Why do astronomers need to have such a large unit? When discussing distances like the size of a galaxy cluster, or a supercluster, or a void, the megaparsec is handy … just as it’s handy to use the astronomical unit (au) for solar system distances (for single galaxies, 1,000 parsecs – a kiloparsec, kpc – is a more natural scale for cosmological distances, a gigaparsec (Gpc) is sometimes used). A quick Google search reveals that 1 Parsec 3.08568025 × 1016 meters. A megaparsec is a million parsecs (mega- is a prefix meaning million think of megabyte, or megapixel), and as there are about 3.3 light-years to a parsec, a megaparsec is rather a long way.
