Development of ring Systems
OK guys - another stoopid question Is there anything about the gas giants that predisposes them to rings (all of them have rings, NONE of the terrestrials do)? There is some chatter about one of Mar's moons potentially shattering into a ring system in about 100 million yrs, but I thought that the ga...

Distance Question revisited
So the diameter of the other planet divided by the diameter of the moon times the earth moon distance gives us the distance that planet would have to be to appear the size of the full moon. Did I phrase that correctly? If that aren't any other wonky factors, i can do the research and crank out my an...

Star Wars instead, huh?
Haven't since Return of the Jedi. Sorry.
But let's talk starquakes and AXPs and SGRs and I might be interested.

Apparent size distance and same distance view question
I was thinking about the Mars hoax and that got me thinking about two interesting (possibly APOD) ideas. First - how far would each of the planets have to be from Earth to appear the size of the full moon. Second - what would the sky look like if they were the distance to the moon. I know that the o...

Illusional Illustrations
No it's not just you (well... maybe, it could be).
Actually, I think APOD sometimes does a disservice with illustrations.
Objects that distant (100 AU) are just not going to be that well lit.

10th Planet
Size is becoming less and less and determining factor in the argument over what is and what isn't a planet. Some people are arguing that sufficient size (and therefore gravity) that results in a round object, should be considered a planet. But what does shape have to do with it. Quaaor, Varuna, et a...

Planet 10?
At about 100 AUs (Astronomical Units = Sun-Earth distances), it is HIGHLY unlikely that the object in question formed there. Too cold, too thinly spread out amount of stuff to accrete into a large body. Possibly like Pluto, it was formed closer in and was scattered outward by Neptune, but at 100 AU,...
