I have taken a look over these forums and various other sites to get answers to this question. However, I want to re-frame it to get information which may be more useful. So, here it goes......... If you have an Earth size planet, where would the best placement for two moons be? In other words I am looking for the ideal orbit and size of these bodies. I understand that having an addition moon would have such effects as differing tides, seasonal effects and lighting. In addition to added cosmic events such as double eclipses or "grand" alignments. From that point I will be looking at developing a standard calendar, similar to our own, which shows the moon phases. I am sure to have questions on that as well, in addition to determining the timing of such cosmic events. Any advice or input is appreciated. If you have suggestions as to where I might find some additional information on developing a realistic solar system I would be grateful.
