Pluto's Smallest Moons Get Names

Kerberos, Styx; but Pluto's still not a planet anymore


Pluto's two smallest known moons have finally been named after an Internet vote was carried out in February 2012. Formally referred to as "P4" and "P5," the two moons are now known as Kerberos and Styx respectively. 

"I was overwhelmed by the public response to the naming campaign," said Senior Research Scientist at the SETI Insititute in California Mark Showalter. The campaign received almost half a million votes from all over the world.
