How did astronomers reach a consensus for a new definition of “planet”?
The world’s astronomers, under the auspices of the International Astronomical Union, have had official deliberations on a new definition for the word “planet” for nearly two years. The results of these deliberations were channelled to a Planet Definition Committee comprising seven persons who were astronomers, writers, and historians with broad international representation. This group of seven convened in Paris in late June and early July 2006.
