Bill Harnett doesn't plan to change the name of its website "The Nine Planets"
Here is his new message:
"The IAU has changed the definition of "planet" so that Pluto no longer qualifies. There are now officially only eight planets in our solar system. Of course this change in terminology does not affect what's actually out there.
This site will continue to be known as "The Nine Planets"; for me Pluto is an honorary planet or maybe a planet emeritus!"
Given the quality of the material available on this website, it's another reminder that the planet definition will not be easily accepted by a large part of the scientific community.
