Well, it's official. Pluto is no longer a planet. According to an AP report that appeared on my Comcast news page scientists have decided on what is a planet. The new definition is:
"a celestial body that is in orbit around the sun, has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a ... nearly round shape, and has cleared the neighborhood around its orbit."
Astronomers have decided that Pluto and other small bodies are to be classified as "dwarf planets."
Now if we can just get them to adopt "rational animal" as the definition of man, it would clear up a lot of things.
