Re: Saturn's rings can disappear too
That was my thought too. Not sure if it's possible in this case though, and I don't have a clue about astrophysics so don't know the answer.
Could our have solar system rotated around this other one quite so quickly (or more likely the other solar system/dust ring rotating)? Even a 1 degree change in angle within a year sounds sounds far too quick to me, but is it possible?
