Favourite spheroid moon of Jupiter? (with pictures)

Io looks like a slice of moldy cheese

I actually liked all these wonderful moons of Jupiter here
and it was very difficult to choose just one out of the four  .

This was to be my order of these four unique moon favorites -

1.  Ganymede - The one I voted for
to me it looks like a most beautiful and perfect marble .

2.  Callisto - I admire it's dreamy
star-like pattern within it .
It's like looking into an entrance
to another galaxy from beyond ours .

3.  Europa - Your choice -
To me it looks like a
large jawbreaker candy
just fun , interesting , and pleasant to view  .

4.  Io - It's like poster napanzee said here
 it does look like moldy cheese .
I wonder if that's where the old saying comes from -
" The moon is made of green cheese " ?

I hope you will please share
some more of these
fascinating moon polls from
other planets with us here again Mr. Dacron  .

Thanks so much for your subject post .

Io has a great industrial finish I can't resist.
