Waspie - I meant posting the story as a thread.  I know I can post a link.  Like the Neptune thread.

You should be able to do that, but nor whilst you are in another topic. Simply go to the relevant forum and towards the top of the page there should be a black button that says "Start new topic". Then post exactly as you would in an existing topic. The only real difference is that you have to fill in the topic title.

S/2004 N 1 is at about twice the distance from Neptune that it rings are, so is not a shepherding moon. it is quite close to being in orbital resonances with its neighboring moons, Larissa and Proteus.
Have you heard the phrase "gravitational kick" before in reference to shepherding moons? If so, can you please explain it to me please.

The object, known by the locals as "Bicho Voador" (Flying Animal), or "Bicho Sugador" (Sucking Animal), has the shape of a rounded ship and attacks people in isolation.

It is amazing that bit by bit our knowledge of our solar system is being slowly rewritten as we discover more.

THIS is what I like seeing our resources channeled towards. Discovering things, not more wars.

It is truly amazing what our probes, that so many have complained about since they aren't manned, are baring so much fruit.  Personally, as a man born in the 50's, I am in awe of the discoveries we have made with the incredible instruments NASA has put into space.  If the Webb makes it, it will change everything.  I guarantee that.  Hubble is amazing and the rescue mission was an absolute heroic achievement at the the time.  Curiosity on Mars kept me up until 3Am and I knew she had made it.  What a mission and she has already exceeded her mission objectives, achieved all her goals and is now motoring on.

When the Webb goes operational we will see a whole new universe.

Believing when there is no compelling evidence is a mistake.  The idea is to withhold belief until there is compelling evidence and if the universe does not comply with our predispositions, okay, then we have the wrenching obligation to accommodate to the way the universe really is.  - Carl Sagan

"There is no difference between Communism and Socialism, except in the same ultimate end:  Communism proposes to enslave men by force, Socialism-by the vote.  It is merely the difference between murder and suicide."  - Ayn Rand

Totally Agree...

Check out this doco if you haven't and see how it was very nearly a huge disaster!

The linked article briefly explains the concept, in the context of the Saturn system. Most of this is applicable to shepherding moons in general.  In brief, momentum is conserved. It can be transferred from a shepherding moon to ring particles, or to another nearby shepherding moon, when they pass each other in their orbits.                                                                   http://solarsystem.n...fm?News_ID=3451
