New article in journal Icarus supports Pluto being classed as a planet

An article published by the University of Central Florida (UCF) reports on a new study published in the journal Icarus supporting Pluto's planet status and arguing that the reason behind the controversial IAU "reclassification" in 2006 is "not valid."

The lead author of the Icarus article is Dr. Philip Metzger of the University of Central Florida Florida Space Institute (FSI), a supporter of the geophysical planet definition. Other authors include Dr. Alan Stern of the Southwest Research Institute (SwRI) in Boulder, Colorado; Dr. Kirby Runyon, of the Johns Hopkins Applied Physics Laboratory (JHUAPL) in Laurel, Maryland; and Dr. Mark Sykes of the Planetary Science Institute (PSI) in Tucson, Arizona.

Unlike most of the four percent of the IAU who voted on this in 2006, these authors all are planetary scientists. Below is the UCF article on their study.
