1. The problem statement, all variables and given/known data If the Earth did not spin on its axis, would the other planets still appear to move across the sky? Justify your answer. 2. Relevant equations N/A 3. The attempt at a solution If the Earth continued to rotate around the sun but NOT on it's own axis then wouldn't we see that there is roughly six months of light and six months of darkness and thus only be able to see the stars for half the year? That being said, since the Earth is still moving in respect to the sun, wouldn't we see the stars/planets (during the six months of darkness) shifting across the sky but not to completion and a lot slower (so not as fast as we do in a 24 hour period but still to some degree)?
