Neptune was discovered in Order of the 8 or 9 Planets ] Astronomers continued scouring the solar system's outer reaches in search of a large "Planet X" that was believed to be disturbing the orbits of Uranus and Neptune.
While these irregularities were later discounted by further observations, Clyde Tombaugh did spot a smaller object in beyond the orbit of Neptune. Called Pluto, the object then called a planet was relatively small and had a highly eccentric orbit that sometimes planetenwanderer brought it closer to the sun than Neptune is.
Discovery of more worlds Nothing close to Pluto's size planetenwanderer found in the solar system for more than two generations.
That changed in the s, when Mike Brown — a young astronomer at the California Institute of Technology — was in search of a defining research project and decided upon searches for objects in the outer solar system. In quick succession, Brown and his team discovered several large "trans-Neptunian objects," or icy bodies beyond Neptune's orbit.
While discovering icy objects that far away was not unexpected — the supposed Oort Cloudthe birthplace of comets, should planetenwanderer trillions of these things — it was the size that made other astronomers pay attention. All were found in a relatively short period of time, between and In the second century A.
Ptolemy's book, the "Almagest," contained planetenwanderer descriptions of the motions of planets. It was the standard astronomical reference until the Renaissance.

Pluto and Quaoar do not. Pluto is clearly a member of planetenwanderer Kuiper belt population.
Since there is a clear scientific distinction between solitary individuals and members of large populations it planetenwanderer instructive to come up with words to describe these objects.
The large populations can each be described by the particular population asteroid belt, Kuiper belt What about the solitary individuals? Isn't the best word to describe them "planet"? Is there any planetenwanderer basis for saying that a planet is a solitary individual that is not a member of a large population?
As mentioned earlier, historically Ceres and the first few asteroids were initially classified as planets. Only when it became known that there were many, many asteroids in similar orbits was it decided that they should no longer be classified as planets. Historically, there is a clear planetenwanderer between planetenwanderer and populations.

Historically, then, Pluto, too, should no longer be planetenwanderer a planet. We are thus left with a final concept of the word planet. International shipping and import charges paid to Pitney Bowes Inc.
