A big question for Orcus & Vanth is whether or not they're made of the same mix of materials. These observations will tell. Stay tuned....

Center-of-mass tells us relative masses of the two. Combined with sizes we get density. Density = what they're made out of.

Eventually we'll use these images to measure the sizes of Orcus and Vanth separately, but also to find the center-of-mass of their orbit.

The ALMA array just took images of the heat being emitted separately from Orcus and from Vanth for the 1st time ever. Can't wait to see!

We were just saying last night how ever since most of the neighborhood got bearproof trashcans we hadn't seen any. Now need bearproof house.

Also, bear, not smart. The OMG KITTENS would take you down fast. Rosie is relentless, particularly with toes.

So a bear just tried to break into our house. Only got the pix of the aftermath. Not cool, bear. Not cool at all.

it is mostly unchanged in the impact. at least in theory.

current theory is that Charon is from an impact, but more of a weird smearing impact that largely left Charon intact.

Most similar to Orcus. Quaoar is kinda midway between Pluto and Charon.

Our New Horizons Google chat, in which I continue to plug poor overlooked Charon, is now archived. Check it out.
