Contention
In the immediate aftermath of the IAU definition of dwarf planet, a number of scientists expressed their disagreement with the IAU resolution. Campaigns included car bumper stickers and T-shirts. Mike Brown (the discoverer of Eris) agrees with the reduction of the number of planets to eight.
NASA has announced that it will use the new guidelines established by the IAU. However, Alan Stern, the director of NASA's mission to Pluto, rejects the current IAU definition of planet, both in terms of defining dwarf planets as something other than a type of planet, and in using orbital characteristics (rather than intrinsic characteristics) of objects to define them as dwarf planets. Thus, as of 2011, he still referred to Pluto as a planet, and accept other dwarf planets such as Ceres and Eris, as well as the larger moons, as additional planets. Several years before the IAU definition, he used orbital characteristics to separate "überplanets" (the dominant eight) from "unterplanets" (the dwarf planets), considering both 'planets'.

Famous quotes containing the word contention:
“In truth, the legitimate contention is, not of one age or school of literary art against another, but of all successive schools alike, against the stupidity which is dead to the substance, and the vulgarity which is dead to form.”
—Walter Pater (1839–1894)
“Contention is inseparable from creating knowledge. It is not contention we should try to avoid, but discourses that attempt to suppress contention.”
—Joyce Appleby (b. 1929)
“Great causes are never tried on their merits; but the cause is reduced to particulars to suit the size of the partizans, and the contention is ever hottest on minor matters.”
—Ralph Waldo Emerson (1803–1882)
