This was the first one I ran into problems with. The octet came easily, but the sestet came out in Wordsworthian form: C-D-C-D-C-D, and split into a 4/2 subset. Not what I wanted, but clearly I didn't try hard enough.

So for this edit, I picked lines and bits of lines out to get the C and E rhymes in preparation to have a C-D-E C-D-E model, with a split in the middle. So I kept "drawn" and "scorn, keeping the first line largely untouched. I kept the sixth line of the sextet unchanged, ditched both "high" and "fly", and created a new rhyme "eye" to go with it, plus a new set of D rhymes: "in the air" and "everywhere". 

Salvaged words and phrases like "vast Jupiter", "east to west", ponderous", "with scorn" to keep the feel of most of what I had written previously, but with the right rhyme scheme. Pity I didn't do it right the first time.

From any of Jupiter's closer moons, the planet must be enormous when it is up! I read somewhere that from Io, it would appear about 25-30 times bigger in diameter than the moon does to us (about 15 degrees, or the distance the moon moves over a whole hour.) I've not been able to find consistent answers for Callisto, which is the furthest away from Jupiter - one picture indicates it would be about 8 degrees, another said less than the size of the moon because it orbit's so far away, so I did the maths and got a figure indicating it would be about 8-10 times apparent diameter of the moon. Either way, it would be big.
