A second of arc (arcsecond, arcsec) is 1⁄60 of an arc minute, 1⁄3,600 of a degree.
When it comes to astronomy, you will find the term "arc second" used in three ways: (1) to express a given distance in declination on a star chart, (2) as a given unit of an astronomical object's size, and (3) as an expression of a telescope's resolving power.
