General Assembly of the International Astronomical Association to-26 issued a decision regarding the definition of a planet. There are three requirements to becalled a planet: (a) orbiting the sun, (b) large enough so as to maintain the shape of(nearly) spherical, and (c) the net there is no other celestial bodies in orbit (quoted by LiveScience blog: Pluto poised for Demotion: Details of Thursday's Vote).
Not the Planet Pluto
Pluto's orbit cuts the orbit of Neptune that Pluto is sometimes closer than Neptune to the Sun in its journey around the sun. This is what causes the need to release the predicate Pluto as a planet and from now on (unless there is a new decision again)included in the small planet (dwarf planet).
Small Planet or Dwarf Planets
The condition is that if (a) orbiting the sun, (b) large enough so as to maintain the shape of (nearly) spherical, (c) does not clean any other celestial bodies in orbit,and (d) instead of a satellite (quoting from the same blog ).
socialization
A strong understanding that Pluto as a planet since the discovery on 18 February1930 by Clyde Tombaugh certainly can not be easily removed. So it is the responsibility of us all to join this new definition socialize. The consequences of that decision is revised in any presentation of information that says Pluto as a planet,such as textbooks, encyclopedias, you are including online media such as Wiki ....
wisdom
Changes or aq prefer to call it as a revision like this was a consequence of thedevelopment of science. The science that we know and we believe now is not a final conclusion. Still banyah things that we do not know the truth. As a term in the X-Files:the truth is out there.
