The question I posted is "Why is Pluto no longer considered a planet?" The answer to this is because it's smaller than all the other planets(even Earth's moon), it's orbit is off, and one of it's moon named Charon is half it's size. So in 2006, scientists proclaimed Pluto a dwarf planet. It's the second largest dwarf planet.
