Since antiquity, the arcminute and arcsecond have been used in astronomy: in the ecliptic coordinate system as latitude (β) and longitude (λ); in the horizon system as altitude (Alt) and azimuth (Az); and in the equatorial coordinate system as declination (δ). All are measured in degrees, arcminutes, and arcseconds. The principal exception is right ascension (RA) in equatorial coordinates, which is m… WebOne parsec is the distance from the Sun to the star under consideration when the parallax angle is equal to 1 arcsecond. Light years are another measure (1 parsec = 3.26 light-years), but this unit is more commonly used by the media. Astronomers use parsecs.
