Pluto discovered in 1960 is the outermost and last planet in our solar system to be discovered, Beyond Pluto is the kuiper belt which consists of billions of icy debris with hundreds of members reaching 100km or more. Pluto's size, composition and orbit suggest that it is an icy asteroid that belongs to the kuiper belt, despite this the International Astronomical Union, astronomy's governing body, announced in 1999 that there's no intension of changing Pluto's classification as a planet. Pluto doesn't really have an atmosphere as it is too small, in fact it is the smallest planet in our solar system. Frozen methane has been detected on its surface, indicating it is bright and icy. Pluto has a moon called Charon that orbits Pluto like a geostationary satellite over Earth showing one side to Pluto and never showing the other like our moon. Scientists believe that humans could live on Pluto in the future if we could somehow warm the planet. For colonisation of any planet to occur information about the planet by the use of probes will need to be sent to find out more about the living conditions.
