The question is a bit tricky! There isn't one specific planet that's a dwarf planet.

Here's why:

* Dwarf planets are celestial bodies that meet certain criteria, but they're not considered "full" planets. They orbit the sun, have enough gravity to be round, but haven't cleared their orbital neighborhood of other objects.

* Examples of dwarf planets include: Pluto, Eris, Makemake, Haumea, and Ceres.

So, instead of saying a specific planet is a dwarf planet, we can say that Pluto, Eris, Makemake, Haumea, and Ceres are all classified as dwarf planets.
