I don't think you'd get much from a spectrum. It's all (likely) reflected sunlight. It's not emitting light, so there are no emission lines, and it's not absorbing light, since there's no atmosphere.

- ars 12y agoYou'd get some from info. Different materials have different reflection curves, especially if they can also image infrared. Just subtract the known spectrum curve of the sun, and check the difference.
- convivialdingo 12y agoThe lack of atmosphere actually helps, as the spectroscopy will be more accurate. I would guess that it's a very reflective crystalline structure. You can see that as the bright structure goes beyond the terminator, it is still visible for a frame, but it completely disappears the frame after. It's hard to say either way though as we don't know the specs of the camera. Lots of materials reflect light differently at wavelengths outside our normal vision.
