There are multiple reasons but to start off i will list the main ones.
Pluto DOESNT/HASNT cleared it orbit. this simply means other objects are in its way...for instance every [pluto] year it passes in through neptunes orbit.
Also it i very small compared to any of the other planets.
then finally it is neither a gaseous planet nor terrestrial it resembles more of a commet.
plutoAnswer: Since Pluto is no longer considered a planet, Mercury is the smallest in out solar system. (I've added the link for a Pluto t-shirt.)
pluto isn`t currently consider as a planet today because in 2006 scinctist decided that pluto is too tiny to be planet and it has a weird orbit and it also isn`t that round to be a planet.But I still want it to be planet but what can i do anyway
In August 2006 the International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet. It was downgraded because it did not meet the three criteria the IAU uses to define a full-sized planet. Pluto meets all the criteria except one: it hasnâ??t cleared its neighboring region of other objects.

A plane mirror.
The cast of T-Bone for Two - 1942 includes: Pinto Colvig as Pluto
Planet Pluto is in solar system and Solar system is in the Universe t, hence Pluto is also in our universe.However Pluto was not part of original Solar sytem but was a comet which was captured in a planetary orbit.

No.
If t is real then [1 to infinity) ie all real numbers from 1 to infinity, including 1 but not infinity. If t is in the complex plane then the domain of t^2+1 is also the complex plane.
The Mighty T Tree
well pluto will never make a complete trip around the sun because ONE:it is not a planet TWO:it will intersect with another planet THREE:i haven't come up with a third reason yet
