Pluto

Pluto repeats an anomaly when compared with the terrestrial planets (Mercury, Venus, the Earth and Mars) or the ogre planets (Jupiter, Saturn, Uranus and Neptune). This icy world is more like a immense asteroid or the satellites of the outer planets; it has even been suggested that Pluto was a satellite that escaped from Neptunes pull. The small size of Pluto feature with its exceed make it very difficult to observe; however, both important discoveries have just been made. In 1976 new spectroscopical observations revealed that the surface of Pluto was covered, at least partially, by set methane.

The infrared spectrum enabled this methane to be identified, besides other kinds of ice, such as ice of ammonia or water. The surface of Pluto, covered by ice, is therefore bright and its reflective power (or albedo) is much greater than we would suppose, thinking that it was all covered by rocks. Knowing its distance from the Earth and its reflection coefficient we can deduce a diam of between 2000 and 2700 kilometers; its mass is thus much less than first-class honours degree estimates.
