Are Xena and Sedna officially planets in our solar system?
Question:
Answer:
Not yet. They are still arguing about it. They may decide to call these new objects planets, or they may demote Pluto to a KBO, or they may just keep arguing.
news to me...to my knowledge, no. IN fact, they are trying to 'deplanetize' one of our planets.
astronomers are trying to define the word planet but it isn't easy. many astronomers favor the reclassification of the bodies in the solar system into three groups, the rocky terrestrials, the gas giants, and the ice dwarfs. there are hundreds of bodies that orbit the sun farther than neptune known. these include bodies like pluto, quaoar, sedna, 2003 EL61, and 2003 UB313 (the official name of xena). this is also called the kuiper belt. pluto was the first kuiper belt object discovered.
