The asteroid Ceres was discovered in 1801; the planet Pluto was discovered in 1930.
In 2006, the International Astronomical Union decided to formally define a "planet"; this had never been formally done before. The discoveries of other distant objects beyond Pluto caused the IAU to finally come up with a rule.
According to the new rule, Pluto, Ceres, and Eris (a newly discovered "tenth planet") were all classified as "dwarf planets".
Of the five dwarf planets, as they are classified today, Ceres was the first to be discovered on 1 January 1801 by Giuseppe Piazzi. For half a century it was classified as the eighth planet.

There are only 8 planets so far (that have been discovered) in our solar system.There are also 4 dwarf planets (these are not proper planets).Starting with the closest to the sun:MercuryVenusEarthMars(Ceres - Dwarf)JupiterSaturnUranusNeptune(Pluto - Dwarf)(Makemake - Dwarf)(Eris - Dwarf)There are probably more - but these are the only ones that have been discovered.
Pluto was discovered in 1930 and dubbed the ninth planet. It was known as the ninth planet up until 2006, when it was reclassified as a dwarf planet. Now there are only eight officially recognised planets in our solar system, with an additional five dwarf planets and several more dwarf planet candidates.

If you list ALL 13 known planets in order, including dwarf planets, they are:1. Mercury2. Venus3. Earth4. Mars5. Ceres6. Jupiter7. Saturn8. Uranus9. Neptune10. Pluto11. Haumea12. Makemake13. ErisDwarf planets also fall under the category of minor planets, of which there are thousands in our solar system. As of 2017, the orbits of 734,274 minor planets were archived at the Minor Planet Center, 496,815 of which had received permanent numbers. The largest minor planet that is not considered to be a dwarf planet is Sedna.

Pluto, Eris, Ceres, Haumea and Makemake are five dwarf planets in our solar system. There are many dwarf planets some discovered and some undiscovered.
Ceres is the smallest dwarf planet. Ceres is a newly discovered planet
Within our solar system, there are 8 planets, and 4 dwarf planets. There are also over 500 dwarf planets from 2 galaxies that have been discovered orbiting other stars.
Of course they are "Dwarf Planets" like Pluto but: Makemake, Haumea, and Eris.
There are 13 in total: Planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Dwarf planets: Ceres, Pluto, Eris, Makemake, and Haumea. It seems likely that several other large objects, such as Sedna, Qaoar and others, will eventually be recognized as dwarf planets. It also seems likely that more dwarf planets will be discovered.
Ceres is the smallest of the so-far-discovered five dwarf planets. She can also be correctly defined as the largest asteroid.
The answer for that is no. Pluto is now comsidered a dwarf planet. However, Pluto have many sisters and brothers. There are many dwarf planets that has been discovered. There maybe, some dwarf planets are still unknown because of the distance.
There are about 480 which have been discovered so far in the universe a handful of them are dwarf planets. Hope this helps!!!!

The are probably many we haven't discovered yet. However currently there are five known dwarf planets.
The other planets are not similar to dwarf planets.
