FAQ?

How do you find the angular size of the sun?

For the Sun, the angular size q = 2R /D radians, where R denotes the Sun's radius and the mean distance of the Sun, D , is 1 AU. The observed angular size of the Sun corresponds to a radius of 695.5 million meters.

How do you find angular size in arcseconds?

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 is about 206,265 arcseconds.

What is the Moon's angular size in arcseconds?

An arcminute can also be divided into 60 arcseconds (abbreviated 60 arcsec or 60"). The angle covered by the diameter of the full moon is about 31 arcmin or 1/2°, so astronomers would say the Moon's angular diameter is 31 arcmin, or the Moon subtends an angle of 31 arcmin.
