WebStellar distances are commonly expressed by astronomers in parsecs (pc), kiloparsecs, or megaparsecs. (1 pc = 3.086 × 10 18 cm, or about 3.26 light-years [1.92 × 10 13 miles].) Distances can be measured out to around a kiloparsec by trigonometric parallax ( see star: Determining stellar distances ).
