    Here's a another image showing the relative sizes of the terrestrial planets and the six largest satelllites, but in color.

    Thanks, but whoa, 7 Mbytes. This one from the same place is smaller.

    And its a tiff file! - I waited for it hoping it was a much better quality than the jpg that GrapesOfWrath found - but I don't have a tff viewer so have to import into word.

    I was right, much clearer. Amazing that Mercury is smaller than Ganymeade and about the same size as Callisto and Titan. Never knew that – or if I did I’d forgotten.

    That jpg print is tiny, isn't it?

    The top row are planets Mercury, Venus, Earth, and Mars, in order. Venus and Earth and similar diameters, Mars is half that, Mercury is about a third. Second row is the Moon, Io, and Europa (all about a fourth of the diameter of the Earth), Ganymede, Callisto, and Titan (all around the size of Mercury).

    Here's a suggestion for you. If you want a nice copy of this but don't want to hold onto the large file, then do what I did. Download the TIF file and then convert it to JPG. Most photo viewing software, even freeware stuff, can do that kind of simple conversion. (I personally recommend Irfanview, a very nice free graphics viewer.)

    When I converted the full size TIF at 100% quality I got a file size of 1.4mb. I also tried shrinking the photo size to 50% and I got a very conveniently sized shot at 393k, perfect for general use. Try it out.
