Did you know (revived).

I thought I would try a Did You Know thread similar to one a few years ago. Maybe people can share some interesting facts, or trivia.

For example...

Did you know that there are more bacteria cells in the human body than human cells?

"A 'reference man' (one who is 70 kilograms, 20–30 years old and 1.7 metres tall) contains on average about 30 trillion human cells and 39 trillion bacteria, say Ron Milo and Ron Sender at the Weizmann Institute of Science in Rehovot, Israel, and Shai Fuchs at the Hospital for Sick Children in Toronto, Canada."

"So to our 30 trillion human cells, we have on average about 39 trillion microbial cells. So by that measure, we’re only about 43% human,” said Rob Knight, director of the University of California San Diego Center for Microbiome Innovation and professor of pediatrics and computer science and engineering."

It certainly does make one wonder what it really is to be human!

* From when it was discovered to when it was declassified as a planet, Pluto did not make a full orbit around the sun.  

(I read recently that there is a move to reclassify it as a planet)

Pluto is now a dwarf planet even though seven moons in the solar system are bigger. The criteria which led to it's declassification as a planet is widely criticized and the voting process used at the time is considered by many to be unscientific. Some scientists are saying the criteria doesn't make sense, but I think it will take a world renowned scientist to prompt a review of the decision. For now little Pluto will have to wait.

There is a dwarf planet called Haumea that spins so fast it can't have a spheric shape. It has been compared to a slightly flattened football, a potato, an egg... It is basically up to you to decide what it looks like, but it is definitely an unusual planet.
