For the next few months, the comet will be in the constellation Perseus, near Cassiopeia. Check out these star maps if you're curious.
The normally sedate Comet Holmes made a bright splash in the sky about two weeks ago, unexpectedly becoming a million times brighter than normal overnight and causing a stir among astronomers.
