There could have been two life-bearing planets but they had to fight over who would get the moon. <3 :_

>>24180849There's a very good possibility that without that impact, life wouldn't exist here.
>>24180869Two life bearing planets orbiting. It's a interesting geometry problem to get light and dark for 12 hours on each side on two orbiting planets with a moon visible to each dark side at any time.
>>24180875Moon in between, planets spiraling...r? :)
>>24180882The moon was created due to the merger of Theia and the Earth.You couldn't have two planets with a moon in the middle. It would create the classical "Three Body Problem". Basically three large-massed things close together could never achieve stable orbits. One would quickly either be shot out or absorbed by one of the others.
>>24180887No... I'm almost certain it's possible to achieve a spherical orbit around the sun with 3 revolving objects.
>>24180921Ah I see what you mean. I thought you meant two planets close together, like within a million km of eachother.
