Gravitational pull in local clusters of galaxies can exist and even contradict larger clusters or the universe as a whole, just in a smaller scale. The passage of time is also localised due to gravitational intensity, too. We know the universe is not expanding at the same rate in different places, as well.
This can happen in sets of complex systems of systems. In your query it somewhat analogous to if you were throwing a ball northbound at 100km/h in a train moving southbound at 50km/h. On a planet circling its star at 107,800 km/h in a total different direction. While the star drags the earth along with other planets in its own orbit in a different direction.
Arch is you know how to use Arch. If lazy then something like Bhodi or Q4OS. I put the latter on a couple of friend’s laptops who recently jumped from Windows. Since it is very Windows-like but it uses less than 400mb of RAM to run on a cold boot.
