  1. Great podcast (and good catch on the IAU committees)!

    I just wanted to say I think Mike Brown would be horrified by your pronunciation of Makemake. I won’t try to transliterate here, but suggest you go to the Wikipedia page on Makemake (the Polynesian deity, not the dwarf planet) and listen to the sound file there.

  3. Pluto is very much a planet, and I encourage everyone to hear both sides of this ongoing debate before blindly accepting one interpretation as fact. Hundreds of professional astronomers led by Dr. Alan Stern, Principal Investigator of NASA’s New Horizons mission to Pluto, have formally rejected the demotion of Pluto, which was done by only four percent of the IAU. Stern and like-minded scientists favor a broader planet definition that includes any non-self-luminous spheroidal body orbiting a star. That gives our solar system 13 planets: Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Haumea, Makemake, and Eris.
