Today's APOD is an illustration of Makemake from a 21 November ESO press release. The release, outlining an article published in Nature the following day, concerned using an occultation of a star to determine whether the dwarf planet has an atmosphere.
Makemake was discovered in March 2005 and classified by the IAU as a dwarf planet in 2008. It has an estimated albedo of 0.74 to 0.80.

Re: Makemake
I still wonder which would have been the best route to take--increase the number on the planet list, or (as we're doing now) increase the categories.

Re: Makemake
Makemake is now known to have a moon, the surface of which is ~1300 times dimmer than Makemake’s. As shown by by an illustration from the Southwest Research Institute, the moon’s about 160 kilometer’s in diameter.
