Thats a bit like asking how long is a peice of string, everyone will give you a different answer and there isn't a right one. The figure newtron has given is about average for the different figures quoted from various sources.

i would say, and dont quote me on this one, that it is probably just longer than any of the others.......hope this helps :-)
