Imagining a clock...the middle of the face where the hands rotate from represents the sun. If at 12 and 6 were to planets, could they inhabit the same orbit around the sun without consequence? I imagine they would not collide as they would be moving at the same rate and in this scenario are at polar opposites of each other. For a manuscript I'm working on I have been puzzled by an imaginary planetary alignment... I am to provide a single planet orbiting a sun with a planetary alignment to happen like the number five appears on dice. The sun and earth planet too be the center dot and the 4 other planets to align at the points of the remain 4 dots on the die. I'm not sure if I'm explaining the problem correctly as I've found most ppl have trouble comprehending the issue. Back to the clock reference, imagine the clock again, the sun and earth being at the middle point and the four remaining planets being at alignment at 12 - 3 - 6 - 9 Preferably they would inhabit separate orbits but with my limited knowledge of the cosmos and its physics i am not sure how to present this in a way that is plausible and believable. I have the imagination to envisage such but not the understanding to make it practical.
