What Is Angular Size In Astronomy? Astronomers use angular measure How do you find angular size in astronomy? Angular Size is measured in arcminutes and arcseconds, which are used to represent angles on a sphere. An arcsecond is 1/3600th of one degree, and a radian is 180/π degrees, so one radian equals 3,600*180/π arcseconds, which
