The expressions 20/20, feet, inches are American centric and are unfamiliar to international readers. Consider using "normal vision" etc. --68.190.226.218 10:18, 15 March 2015 (UTC)

According to en:Visual acuity, use of "20/20" and the Snellen chart are standard in measurement of human visual acuity and not purely "American centric". cmglee (talk) 15:31, 15 March 2015 (UTC)

Moon size

The min and max size given for the moon differ with what I've read elsewhere (34'6"-29'20") and differ with Wikipedia's Moon page (34.1'-29.3'). I tried to check the original NASA source page but it seems to be gone. But it wouldn't be the first time I saw conflicting info on NASA pages, I saw so many different numbers given for the orbital periods of planets...

Could it depend on where on Earth it is measured from? Earth's 6300+ km radius is around 1.6% of its distance from the moon, so someone with the moon overhead should see a 1.6% larger moon than when it is just above the horizon. Refraction also changes its apparent size. cmɢʟee ⋅τaʟκ 20:43, 17 August 2022 (UTC)
