"...Instead, it will be reclassified in a new category of 'dwarf planets,'..." DOH!

In the boring world of astronomy where discoveries are few and far between, they have to do some sort of marketing to make it a little bit more... interesting?

So... Science really is not an "exact" science.

So... Science really is not an "exact" science.

just like meteorology, they call that a science too and we all know how accurate weather forecasts are

so what is the new defination of a planet? that it must have gravity?
