Are there other dwarf planets in the solar system?

Yes, there are other dwarf planets in the solar system besides Pluto. Ceres, located in the asteroid belt between Mars and Jupiter, is the largest and was the first to be discovered in 1801. Other known dwarf planets include Eris, Makemake, and Haumea. These bodies have been classified as dwarf planets because they meet certain criteria established by the International Astronomical Union (IAU), including orbiting the Sun, having enough mass to be spherical, and not being a moon or an asteroid. However, there are several other objects that have been identified as potential dwarf planets and are currently being studied.
