- 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).
