WebR will be in units of angular measure called radians ( 1 radian = 57.3 degrees). You cannot see details with your eye, with a camera, or with a telescope, that are smaller than the Airy Disk size for your particular optical system. The formula also says that larger telescopes (making D bigger) allow you to see much finer details. For WebFor an observer on the Earth, the angular diameter of the Moon and the Sun are quite similar ( ~ 0.5 o = 30 arcmin ). In reality, the Sun’s physical diameter is 400 times bigger than the Moon, while the Moon is ~ 400 times closer to the Earth. Actual size of the Sun and Moon: the Sun’s diameter is 400 times the diameter of the Moon.
