More museum news for the Demote Pluto front: in addition to the removal of Pluto from the list of planet symbols, the Smithsonian National Air and Space Museum’s Exploring the Planets exhibit has updated some of its solar system displays to clarify Pluto’s new status as a “Dwarf Planet,” and added an “In Memoriam” poster to explain the classification change.

Many thanks to the NASM for being frank and sensible about the progress of our understanding of the solar system while also graciously giving acknowledgment to Pluto’s historical status in the course of human astronomical study, and special kudos to the exhibit copywriters for avoiding BTQ abuse.
