Bennechi: Binary KBO Sila/Nunam now enjoying mutual events. Slow orbit (>12d) means events last ~10hours! Need multiple telescopes. #DPS13

RT @lukedones: Nice talk by Scott Sheppard, but this continues to be the story of the search for more Sednas: http://www.sadtrombone.com/ #dps13

Q for TNO people at #DPS13: what's the difference between "scattered" and "scattering" objects?

Alexandersen: surveys 3 different types of objects (SDOs, Plutinos, Trojans) confirm objects <100km scarce. These types "born big" #DPS13

Brown: Small KBOs are under-dense. Big KBOs are dense. Origin problem: you can't build big KBOs out of smaller ones. No explanation. #DPS13

Parker: the inclinations of Neptune trojans suggest that Neptune migrated into a disk that was *already* scattered. (Weird.) #DPS13

That's it for Galilean satellites at #DPS13. Will watch a couple of Jupiter talks, then move to TNO room.
