Then no, you don't understand relative position. Our speed and in fact our entire solar system is incredibly tiny when we are talking about the scale of the distance between stars. Our local movement isn't going to change which stars we can see, nor will it make them streak (or spiral) across the sky. Over the course of a century, the relative position of the Solar System to a distant star might only change by 1 degree. Depending on how far away the star is, it might take 100,000 years before our relative position changes by 1 measly degree. At those speeds, any spiral or streak would not be noticeable during the course of a single night.I’m actually glad you posted that picture although a timelapse shouldn’t be needed to make the stars appear as trails if we’re moving as fast as we are. I understand relative position. It’s like driving down the highway and seeing a mountain far off in the distance appear to move slow. Trouble is the speed that we move around the sun as well as through the galaxy is too fast for any of that to be applicable. Take that time lapse pic. If earth is spinning, and then we’re also orbiting the sun, those trails should look like spirals instead of curved lines..
On the other hand, a rotating planet will cause the stars to streak, because our relative position turns 360 degrees in a short 24 hour period.
