Do you want the axes also to "fade away" or only the sphere?

Only the sphere.

If you want only a radial fading, then the example just before section 23.4.2 may be the way to go.

Another option is to slightly slightly modify the fuzzy circles from the shadings library. (I merely copied and slightly modified the fuzzy circle fading from the library to give you immediate access to the transparency levels at different distances. I am not claiming that my choice is particularly nice, but in the end you need to decide yourself what suits you best. The number 23 does not really represent a percentage, but if you play basketball you may understand why I picked it. ;-)

replace the shade line with
`node[circle,shading=radial,outer color=gray!30,inner color=black!80, minimum width=14.5cm];
