Geologic history
Pluto formed about 4.1 billion years ago,it was 89% its current mass,and 93% its current radius,it stayed this way until 3.4 billion years ago,when a massive object,560 miles in diameter crashed into it,this impact melted its surface,adding mass to Pluto,this also created Pluto largest moon, Charon.Pluto was a waterworld for another million years before the heat of the impact left and it grew cold again.

Modern history ====

In 2046,After the Planetary Re-refinement,it was Promoted due to the Drop of the Dwarf Planet Catalog

The first manned mission took part in 2131, followed by a colony in 2198,it achieved independence and became the kingdom of pluto
