About Parsecs

A parsec (pc) is approximately 3.26 light years or 30.86 trillion kilometers, defined as the distance at which one astronomical unit subtends an angle of one arcsecond. Despite being less familiar than light years, parsecs are preferred by professional astronomers because they relate directly to stellar parallax measurements - the apparent shift in a star's position as Earth orbits the Sun. Most nearby stars are within a few dozen parsecs, our galaxy is about 30,000 parsecs across, and distant galaxies are measured in millions of parsecs (megaparsecs).

About Nautical Miles

A nautical mile (nmi) is equal to 1,852 meters or approximately 1.15078 statute miles, based on one minute of arc along Earth's meridian. This unit is the standard for maritime and aviation navigation worldwide because it directly relates to Earth's geometry, making navigation calculations simpler. Ships and aircraft measure speed in knots (nautical miles per hour). The distance between parallels of latitude is almost exactly 60 nautical miles. International maritime law uses nautical miles to define territorial waters and exclusive economic zones.
