Use the information from the article to answer the question.PlutoWhy is Pluto now called a dwarf planet?

Answer:

Pluto is now classified as a dwarf planet because the discovery of the object Eris in 2003 led astronomers to redefine the characteristics of a planet. They determined that due to Pluto's size and location (specifically its failure to clear its orbital path of other objects), it does not meet the criteria for a major planet and is instead categorized as a dwarf planet along with Eris.
