![]() more definition+In relation to the base unit of => (meters), 1 Parsecs (pc) is equal to 3.0856775814914E+16 meters, while 1 Light Years (ly) = 9461000000000000 meters. A star seems to move a little bit back and forth during the year viewed from Earth. It is a very powerful tool used to determine the distance between stars because the angles between the stars are very important. Earth circles the Sun, making one complete orbit per year. The parsec is an astronomical unit of length and is equivalent to around 3.26 light-years. more definition+Ī light-year (abbreviation: ly), sometimes referred to incorrectly as a light year, is a unit of length used informally to express astronomical distances. A: A parsec, or parallax second, is defined as 3.26 light-years because of how it is measured. One parsec is the distance at which one astronomical unit sub. How to convert Parsecs to Light Years (pc to ly)?ġ x 3.2614708608935 ly = 3.2614708608935 Light Years.Īlways check the results rounding errors may occur.Ī parsec (symbol: pc) is a unit of length used to measure large distances to objects outside our Solar System. The Voyager 1 probe, launched in 1977, is the most distant manmade object from Earth. ![]() The base unit for length is meters (SI Unit) Type in your own numbers in the form to convert the units Quick conversion chart of parsec to lightyear 1 parsec to lightyear 3.26156 lightyear 5 parsec to lightyear 16.30782 lightyear 10 parsec to lightyear 32.61564 lightyear 15 parsec to lightyear 48.92346 lightyear 20 parsec to lightyear 65.
