There aren't many other options.  To lose energy, you need to knock into
something.  You have the choice of lots of little things (the atmosphere) or
one big thing  (Neptune itself).  But I'm really no expert on orbital mechanics,
so I'll some physics jock give more details (should be plenty of folks who 
know here in sci.space).
