	On Oct 23, 2007, J. A. Henríquez Santana in the Canary Islands and Ramón Naves in Barcelona noticed an impressive spectacle, a bright and large comet gleemed through the bright full moon in the constellation Perseus. This was not a new comet, yet it was a suppossedly boring one. The comet 17P Holmes was supposed to be a meagre 17th magnitude, far too dim for most		On Oct 23, 2007, J. A.

	Most of the comets lay at the distant reaches of our system in a hypothesized [[w:Oort cloud\|Oort cloud]]. At the very edge of the solar these comets orbit if very large loops around the distant reaches of our solar system. The passing of nearby stars, or other objects can create alter their orbit, sending them speeding towards the inner reaches of our solar system. these comets then typically retain very large orbits such that these comets will not return (once seen in the inner solar system) for many thousands of years.

	Occasionally inteferences with the large gas giants of our solar system (jupiter and saturn) will further alter their orbit. These comets commonly roam in an area called the [[w:Kuiper belt\|Kuiper belt]], that surrounds the last planet Neptune. The orbits of these comets vary highly from the diminuitive comet Encke (3 years) to the famed comet Halley seen only once maybe twice a lifetime (76 years).
