| The fact remained that the Rage fleet was within a parsec of Nova. |
| Therefore, one parsec equals 3.26 light-years. |
| This unit of distance is termed the parsec, defined as the distance of an object whose parallax equals one arc second. |
| This equation establishes the connection between the apparent magnitude, m, the absolute magnitude, M, and the distance, D, measured in parsec. |
| But cosmologists are so comfortable with millions and billions that none of them feel the urge to invent a unit much beyond the light-year or the parsec. |
| They are commonly measured in parsecs, where one parsec is equal to about 200,000 AU or about three lightyears. |
