Default How many known moons do the various planets have?

I've been reading the Uranus tread, and how scientist keep discovering more moons arond Uranus.

I am wondering how many known moons some of the other planets have? Where can I find those kind of updates?

What are they named? Have they been keeping the same naming scheme that was used in naming the other moons.

What I know, or think I know.

Mercury-0
Venus-0
Earth-1
Mars-2
Jupiter-More than 16--(The last number I saw in writing--I am sure that the number is much higher) All of the early discovered moons except one were named after the lovers of Zeus.
Saturn-At least 18--(The last number I saw in writing--I am sure that the number is much higher). The early discovered moons seems to be named after various ancient Gods.
Uranus-27 Moons named after characters in Shakespare and Pope's writing.
Neptune-8? Not sure what the moons are named after.
Pluto-1


If you know that any of my numbers are wrong, please correct me. I am sure that the numbers I have listed for Jupiter and Saturn are much much to small.

Thanks for your help.

Since Neptune was the god of the sea, the moons are named after lesser mythological beings (merpeople, sea nymphs) associated with the sea.

They've found so many moons of Jupiter, that I understand they now have to name them after the lovers of Julio Inglesias.....

A question I have is when Casini gets to Saturn and starts to resolve the rings, at point will a ring particle no longer be considered a particle but a moon?

Scott Sheppard has pages a little more informative than the Planetary Society one:

Good question. There's a touch of this issue already with Jupiter: Galileo reportedly photographed seven "rocks" near Amalthea in a flyby last year; the issue of whether or not to consider them satellites may not be confronted head-on since orbits couldn't be determined (at least as of the last I heard).[/url]
