WebNow, the distance from the earth to the sun varies from about .98 AU to 1.02 AU, so using 1 AU is at least 98% accurate for the length of the adjacent side. Since it is just a multiplicative factor, this translates to at least 98% accuracy for the final answer, regardless of distance. 4 comments ( 91 votes) Upvote Downvote Flag more Show more... WebThe first parallax determination was for the Moon, by far the nearest celestial body. Hipparchus (150 bce) determined the Moon’s parallax to be 58′ for a distance of approximately 59 times Earth’s equatorial radius, as compared with the modern value of 57′02.6″—that is, a mean value of 60.2 times. Lunar parallax is directly determined from …
