DESCRIPTION:Giant\, planetary scale\, impacts can occur anywhere in a plan
 etary system\, from the innermost to the outermost regions.  Giant impacts
  produce debris discs with distinctive features\, such as dramatic\, large
  scale asymmetries.  I will discuss the origins and nature of these asymme
 tries and their lifetimes and show that at large orbital radii these featu
 res will be long-lived and detectable.  A number of known debris discs dis
 play large asymmetries and I will show that giant impacts can provide a go
 od explanation for the asymmetries in some of these systems.
