Andromeda is pretty close to us. In fact, we're going to collide with it in a few billion years. After that, what little remains of our solar system by then, might end up like one of these orphaned stars.
So if Andromeda is already difficult to see by us, that gives some indication of what's going to be visible from a planet that is much further away from anything, than even that.
- dalke 12y agoThe premise in the g'parent comment is "If most such stars are still within the Galactic groups ...". This assumption is reasonable given the hypothesis expressed in the article: "Bock suspects that a lot of these renegade stars could have come from relatively lightweight galaxies, which can lose hold of their stars more easily than more massive galaxies." Our Local Group has a diameter of ~10 megalight-years . Andromeda is 2.54 MLy away. Thus, given the premise, and assuming that our own cluster is "typical", it's unlikely that a renegade star is all that much further from a galaxy like ours or Andromeda than we are from Andromeda.
