The diameter of the full Moon & the Sun is about 30' (thirty arcmintes), I say about because all orbits are eliptical not circular, this includes the moons orbit around the Earth and the Earths orbit around the sun, therefore the distance from the Earth/Moon and Earth/Sun varies which makes the appearant diameter of the Sun and Moon change over the course of a Lunar cycle and over the year, but it averages 30'. This is also why there are annular and total eclipses of the Sun. : Can anyone tell me the apparent diameters of the moon and sun are as viewed from the equator? (Presumably this is measured in degrees, mins, seconds).
