Labels:text | font | screenshot | paper | black and white | document OCR: IN 1766, THE PRUSSIAN ASTRONOMER Johann Titius (1729-1796) devised a formula for gauging the distances of the planets from the Sun in astronomical units (AU; 1 AU is equal to the distance of the Earth from the Sun, which is 149,597,870 km or 92,955,730 miles). The formula was published by the German astronomer Johann Bode (1747-1826) in 1772. It uses the symbol D for a planet's distance from the Sun and the symbol N for one of the numbers in the following sequence: 0, 3, 6, 12, 24, 48, 96, 192. Use the first number in the sequence to find the distance of Mercury, the closest planet to the Sun; use the second number to find the distance of Venus, the next planet out, and so on. To do this, replace the N in the formula with the appropriate number from the sequence, add four to the number, an ...
