Pluto Day

Pluto Day is February 18th

Pluto might not be a planet anymore, but it is a dwarf planet worthy of recognition on its birthday. Pluto was discovered by Clyde W. Tombaugh, an American astronomer on February 18th 1930. At the time it was named the 9th planet, a title it would hold for 70 years before being redefined as a dwarf planet in 2005. You can celebrate this holiday by learning more about Pluto and what exactly its new classification as a dwarf planet means.
