First Surface Observations of Oort Cloud Objects

Spectrum of C/2013 P2 (Pan STARRS) from the visible (blue points) to near infrared (red points) compared to other solar system small bodies: comets (represented by comet 6P/d’Arrest), Trojan asteroids, outer asteroid belt red D-type asteroids, and ultra-red Kuiper belt objects (TNOs). This shows that C/2013 P2 looks very different from other small body surfaces.
