    • So average temperature of Earth is 7.2°C. On contrary , average temperature of Pluto is -234°C. Pluto is very cold.
    • The other big differences is volume of planets. The volume of Pluto is one percent of Earth. Because the mass of Pluto is only 0.02 percent of Earth. Pluto is a planet which is colder, smaller and lighter than earth.
