Sorry to hijack this thread back to something serious, but...
I was looking at a plot of where stuff is in the outer solar system at http://cfa-www.harvard.edu/iau/lists/OuterPlot.html (link provided so graciously by edstrick on the Pioneer/Asteroid Belt thread), and I noticed that there is a big gap in the Kuiper Belt right where New Horizons is headed. Is this some kind of an observational bias, or is there a real dynamic effect, some kind of scattering by Neptune, that is clearing out the exact part of the belt that we're going to visit? Does this mean that NH is less likely to find a big juicy target after Pluto? Bart |

That's just an observational effect. NH is headed toward Sagitarius, the galactic center.
The starfields are dense there, so observers avoid them to ease their needle in the haystck hassles in finding KBOs. The KB itself has no such gap. -Alan |

A random note on that outer planets plot: There is a lot of "structure" in the Kuiper belt that consists of approximately radial lines of objects separated by zones with fewer objects. This is an amusing selection effect... wher objects were found in a deep search, separated by areas where the search wasn't as deep.
Even more amusnig....some of the line-ups are NOT radial toward the sun.... because the inner objects have moved slightly further in their orbits since that radial zone of objects was discovered than the objects further out. |

Perhaps now would be a good time to reask a question I asked earlier:
QUOTE (Holder of the Two Leashes @ Jan 16 2006, 09:52 AM) When they do start that search, Pluto (and any KBO targets) will be smack in the middle of the milky way in Sagitarius. This is an area normally avoided by planetoid hunters in the past, because of the dense star field. I wonder how they're going to address this issue? You need very good resolution, on the order of nearly perfect seeing from the ground, to pull anything out of the background.

I find the animation of the orbits of the discovered objects to be amusing: http://cfa-www.harvard.edu/iau/Animations/OuterSmall.gif Lots of comets that were discovered in the inner solar system extrapolated back in time... very clearly indicating how much must be undiscovered. |

In Arthur C. Clarke's novel The Hammer of God, a bomb is detonated that reveals where every minor body is in the Sol system. I cannot remember the details much beyond this, can someone help here and would such a plan be feasible?
http://en.wikipedia.org/wiki/The_Hammer_of_God -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |
