From Wikipedia, the free encyclopedia
A parsec is the distance from the Earth to an astronomical object which has a parallax angle of one arcsecond.For other uses, see Parsec (disambiguation).
See 1 E16 m for comparable lengths, and scientific notation for an explanation of the notation used in this article.
The parsec (symbol pc) is a unit of length used in astronomy. The length of the parsec is based on the method of trigonometric parallax, one of the oldest methods for measuring the distances to stars.
The name parsec stands for "parallax of one second of arc", and one parsec is defined to be the distance from the Earth to a star that has a parallax of 1 arcsecond.
