I don't see where r3roble and I disagree, so I truly wonder what is to trigger this supposed debate?

yes... i agree with rodsky... and he knows a lot and can help me learn...he he
guys, walay away, hap..hihihihii
mangadto nalang tag outerspace..lupad2 ta..hehehehe
..asteroid na d i ang pluto? so d na pluto iyang name? ngeee... so 8 nlang ang planets? ..hmmm... karon pa ko..![]()
No. Pluto is not an asteroid, the formal classification of Pluto now is "dwarf planet", specifically, one of several "Plutoids". I know it's confusing, but to someone immersed in astronomy such as me, the nomenclature makes perfect sense, and reduces clutter when tallying the objects in the solar system within the bounderies of the Heliopause.
From the IAU:
A new class of objects and how to define a planet
The IAU has been responsible for the naming and nomenclature of planetary bodies and their satellites since the early 1900s. As Professor Ron Ekers, past president of the IAU, explains:
Such decisions and recommendations are not enforceable by any national or international law; rather they establish conventions that are meant to help our understanding of astronomical objects and processes. Hence, IAU recommendations should rest on well-established scientific facts and have a broad consensus in the community concerned.(read the full article)
The IAU decided to create a committee to gather opinions from a broad range of scientific interests, with input from professional astronomers, planetary scientists, historians, science publishers, writers and educators. Thus the Planet Definition Committee of the IAU Executive Committee was formed and quickly went about preparing a draft resolution to put to the members of the IAU. After the final meeting in Paris the draft resolution was completed. One crucial aspect of the resolution is described by Professor Owen Gingerich, Chair of the IAU Planet Definition Committee: "On the scientific side, we wanted to avoid arbitrary cut-offs simply based on distances, periods, magnitudes, or neighbouring objects".

The final resolution
The first draft proposal for the definition of a planet was debated vigorously by astronomers at the 2006 IAU General Assembly in Prague and a new version slowly took shape. This new version was more acceptable to the majority and was put to the members of the IAU for a vote at the Closing Ceremony on the 24 August 2006. By the end of the Prague General Assembly, its members voted that the resolution B5 on the definition of a planet in the Solar System would be as follows:
A celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.

Dwarf Planets, plutoids and the Solar System today
The IAU Resolution means that the Solar System officially consists of eight planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. A new distinct class of objects called dwarf planets was also decided on. It was agreed that planets and dwarf planets are two distinct classes of objects. The first members of the dwarf planet category are Ceres, Pluto and Eris, formerly known as 2003 UB313. Eris was named after the IAU General Assembly in 2006 (read more) Eris is the Greek god of discord and strife, a name which the discoverer Mike Brown found fitting in the light of the academic commotion that followed its discovery.
The dwarf planet Pluto is recognised as an important prototype of a new class of Trans-Neptunian Objects. The IAU has put given a new denomination for these objects: plutoids.
Today the resolution remains in place and is a testament to the fluid nature of science and how our view of the Universe continues to evolve with changes made by observations, measurements and theory.
This basically means one thing--if a new object, orbiting the sun, is found to be equal to or larger than the dwarf planet Ceres, but is located between the Sun and Uranus, then it's a merely a "Dwarf Planet". However, if it resides within the vicinity of Neptune, and beyond, then it's a "Dwarf Planet" but with a specific designation of "Dwarf Planet: Plutoid"
