Webb14 apr. 2013 · This meant astronomers could define the distance from the Earth to the Sun as one astronomical unit (1 au). Thus, Venus was 0.72 au from the Sun, Jupiter was 5.2 au, Saturn was 9.5 au, and so on. But this only gave the proportional distance. To find the actual distances of the planets, astronomers needed an accurate measurement of 1 au. Webb14 sep. 2024 · Venus, Earth and Mars at 3cm Jupiter at 6cm Saturn, Uranus and Neptune at 4.5cm We’ll place our planets in a straight line, but they would really extend out by 10m in all directions from our star. The distance between the Sun and the Earth is 150,000,000km; this is 1 Astronomical Unit (AU). WebbIn 1896, Simon Newcomb's value, a distance from Earth to Sun of 92,702,000 plus or minus 53,700 miles, was adopted by the international scientific community. Today most textbooks report the Astronomical Unit (or AU) as "93 million miles." The Venus transit has continued to yield fascinating new information for scientists and the public. charity ranker
