QUOTE A whole series is needed, really... I've thought about something along the concept of "Powers of Ten" going from the Sun to ??whatever. Or maybe from ??whatever to the Oort cloud... That might be too much though... --Bill -------------------- |

Here is a scale diagram of the satellite orbital distances. The planets are to scale, but each satellite is only one pixel (so dust off your screen). This includes every satellite over some threshold (I forget what that was)... plus Phobos and Deimos. The real upshot here is the revelation that Iapetus is so far out! Also, it's interesting to see that the orbits of Deimos and Charon would fit inside the gas giants.

QUOTE (JRehling @ Nov 19 2005, 09:52 AM) Here is a scale diagram of the satellite orbital distances. The planets are to scale, but each satellite is only one pixel (so dust off your screen). http://www.cogsci.indiana.edu/farg/rehling...moon-orbits.gif I think that it needs a few labels! Here's what I can figure out: MERCURY VENUS EARTH: The Moon MARS: Phobos, Deimos JUPITER: Amalthea, Io, Europa, Ganymede, Callisto SATURN: Janus(?), Mimas, Enceladus, Tethys, Dione, Rhea, Titan, Hyperion, and (way over on the right) Iapetus URANUS: Miranda, Ariel, Umbriel, Titania, Oberon NEPTUNE: Larissa(?), Proteus, Triton PLUTO: Charon The cutoff appears to be around 95km radius. Now, if I may be so bold as to render the smallest grumble of disapproval about this fine diagram: I realize that it's more artistic to depict Saturn with tilted rings, but in this particular case, when you are showing the satellite systems, and considering that the rings are really part and parcel of Saturn's satellite system and not merely an adornment, it might be more appropriate to straighten them out and get the rings (and Saturn's equator) in line with the satellites' orbital disk. |

I have been searching and haven't found much in the way of Pallas imagery. Here is an image I constructed through super-res processing of an HST sequenc. The disk is only a few pixels, so it does not show surface details (it missed the planetary camera chip, so it is imaged by the Wide Field portion of WFPC2. The only thing of sigificance is that it does seem to be a pretty round little world, which is consistent with occultation data.
