Only 78 days to Stein encounter ! I can't believe I forgot about this event.

"Can anyone point me to a "chance alignment" of 7 or so craters out of the largest 20 or 30 on any other asteroid or moon? "
Famous example: the apparent chain of six large craters extending south from Ptolemaus on the central meridian of our moon, long touted as proof of their internal origin. Look at the 'rivers' I mentioned above. Purely random chains you can see every day. Look at stucco. Randomness includes lots of apparent patterns. Phil -------------------- ... because the Solar System ain't gonna map itself.

Look at the 'rivers' I mentioned above. Purely random chains you can see every day. Look at stucco. Randomness includes lots of apparent patterns. Phil The large craters south of Ptolemaus are much smaller relative to the size of the moon than the craters on Steins relative to Steins. So the likelyhood of finding some chain like this somewhere on the moon is much higher than finding what we see on Steins. |
