    “There are two types of countries in this world. Those who use the metric system, and those that have been to the moon.” Although I can’t remember where I found this quote, it immediately popped into my head when I thought of the metric system in the US.

This needs to be done because they are the units Kepler’s Third Law require in order to be able to obtain the mass of “Object X” properly. The units given in the introduction are in kilometers and days. Therefor the radius has to be converted to Kepler’s Third Law values, so from kilometers to meter and days…

Another variable that had to be tested was how many fins to use based on the ideal mass for the rocket. In a rocket it is normally true that it will fly the farthest if the mass is closer to the front,…
