It describes the relationship between distance of planets from the Sun, and their orbital periods (the time period of its orbit).]]> 2019-04-20 02:24:28 UTC https://padlet.com/parkerch2/uzql82xjao5h/wish/352827149 parkerch2 https://padlet.com/parkerch2/uzql82xjao5h/wish/352827295 2019-04-20 02:26:41 UTC https://padlet.com/parkerch2/uzql82xjao5h/wish/352827295
