Science Lesson Plan: This is a really fun lesson plan to combine with an art project. The distances between the planets become tangible and surprisingly far! The Solar System The distances between the nine planets are vast! We used Bode’s Law to determine the ratio of the distances between each planet and reduce it to a manageable size. To find the mean distances of the planets, beginning with the following simple sequence of numbers: {0, 3, 6, 12, 24, 48, 96, 192, 384} With the exception of the first two, each integer is simply twice the value of the preceding number. Then, add 4 to each number: {4, 7, 10, 16, 28, 52, 100, 196, 388} Then divide each number by 10: {0.4, 0.7, 1.0, 1.6, 2.8, 5.2, 10.0, 19.6, 38.8} The resulting sequence is very close to the distribution of mean distances of the planets from the Sun: Body Actual distance (A.U.) Bode's Law <A.U.)< td> Mercury Venus Earth Mars 0.39 0.72 1.00 1.52 Jupiter Saturn Uranus 5.20 9.54 19.19 0.4 0.7 1.0 1.6 2.8 5.2 10.0 19.6 We equated one Astronomical Unit with one centimeter. In conclusion, this is a very useful activity to demonstrate the sizes and distances of the planets.
