[space] Methone, an egg in Saturn orbit? … fascinating blog entry with pictures about a recently discovered moon of Saturn … ‘Methone is really shockingly round. Some of the other small moons that orbit near the rings have a smoothed appearance, but they all still have some craters or some topography. The smoothness probably results from these things collecting dust, a substance that there is a lot of in this part of the Saturn system, but it’s kind of hard to understand what could make the dust slide around to fill every topographic low on this little world, covering it with what’s essentially a global ocean of very puffy dust. I think the roundness tells us that whatever Methone is made of, that material behaves like a liquid — it has no strength to hold any shape whatsoever.’
