矮行星 Dwarf Planets

行星,自2006年8月24日國際天文聯會的歷史性決定而產生,除了冥王星外,穀神星、不和女神星均為矮行星,在矮行星的定義中也避免不開凱伯帶天帶和其他太陽系小天體的討論,冥王星已經被定義為矮行星,至於矮行星是不是行星,不是這講座討論的內容。反而,這講座會討論凱伯帶、經典凱伯帶天體、共震凱伯帶天體、離散圓盤天體、不和女神星的發現等。

Dwarf Planet, this term established since the historical decision of IAU in Aug 24, 2006. Apart from Pluto, Ceres and Eris also classified as dwarf planets, and in the discussion of dwarf planets, the knowledge of KBOs and other small solar system bodies cannot be avoided. Now, Pluto is firmly classified as dwarf planet, however, whether dwarf planet should be considered as planet is not the aim of this lecture. In this lecture, KBOs, classical KBOs, resonant KBOs, scattered disk objects, discoveries of Eris are discussed.
