I used to be a 'Pluto planet hugger' myself, but Pluto has such an elongated orbit that to me it does not constitute itself to be a planet, but one that was was too big and too far to have been 'captured' by our giants and sun. That's my take on that at this point.

And then there's this:

[Nestled between Mars and Jupiter, Ceres was in just the right spot. So astronomers called it a planet. Piazzi initially named the new planet Ceres Ferdinandea after the Roman goddess of the harvest and King Ferdinand IV of Naples and Sicily. Ferdinandea, however, was later dropped.

Ceres's discovery was just the beginning of a landslide of small bodies spotted between Mars and Jupiter. A year after Ceres was discovered, astronomers found another body between the two planets that was almost as bright as Ceres. Heinrich Olbers unexpectedly found the second body, which he called Pallas after Pallas Athena, an alternate name for the goddess Athena.

Many astronomers realized that neither Ceres nor Pallas fit the conventional idea of a planet because their disks were so small they could only be resolved through telescopes. Because of their star-like appearance, Sir William Herschel coined the term "asteroid" for such bodies, writing in 1802: "They resemble small stars so much as hardly to be distinguished from them, even by very good telescopes." Herschel, therefore, argued that Ceres and Pallas were different from other planets.

Most other astronomers, however, disagreed. These two new additions to the solar system were listed with the rest of the planets.

The rush of small bodies continued to pile up. Astronomers nabbed Juno in 1804 and Vesta in 1807. The growing list of small objects raised concern that the asteroids were debris from a planet that had somehow disintegrated. Nevertheless, Juno and Vesta joined Ceres and Pallas as planets.

By the 1820s, astronomers counted 11 planets in the solar system. Introductory astronomy texts of that time listed the planets as Mercury, Venus, Earth, Mars, Vesta, Juno, Ceres, Pallas, Jupiter, Saturn, and Uranus.

Astronomers found another body, Astraea, near the end of 1845, almost 39 years after Vesta was spied. Three new objects were spotted in 1847. By the end of 1851, there were 15 known bodies between Mars and Jupiter. ]

Shape counts for something, yes, but it's where, WHERE, these bodies are orbiting that counts as well.

Bottom line, if they are round or not, if they are orbiting something, be it the sun or a huge planet like Saturn, if they are round or not, they will still be labeled as a moon or captured asteroid.
