It has a very rapid rotation so a day on Haumea is only three and nine tenths hours. No moons are none to the dwarf planet, but there is red spot that stands out possibly because it's richer in minerals. I don't thein Haumea needs to be recognized as a planet. It sparks nothing important or why the change should be made.
The last dwarf planet is Eris, and it may be the largest. There is enough of a margin in the measurements for Eris to be larger than the current largest dwarf planet Pluto. Eris has only one known moon and was once tested to be the tenth planet in our solar system. I don’t think any decision on whether or not Eris becomes a planet is matters or doesn't. It has reasons to become on but also some why it should stay a dwarf planet. For now though, I personally think it's good were it is.
In summary there are five dwarf planets out there and they all have many special qualities, but some are qualities in my opinion good enough to be a planet and some should just stay a dwarf planet. Makemake and Haumea have no reason to become a planet. Dwarf planets like Pluto and Ceres should be a focal point in the decision of new planets. Eris should be considered but not pondered too much on. The dwarf planets have all been named this but some were deservedly given it while others should be
