Pluto is a Planet.
The big debate has come to an end, after New Horizons discovered during its fly by and passing that Pluto has an 50-80 Km high methane rich atmosphere. What more was found was an area called the heart with moving ice flows and mountain ranges 3 miles high.

Genesis 1:1-11, John 3:3-8, 1 Corinthians 15:38-42.
