The Caltech astronomer Mike Brown identifies nine Solar objects that he calls dwarf planets. the first five on the list below are the only recognized by the International Astronomical Union (IAU):
- Eris
- Makemake
- Haumean
- Pluto
- Ceres
- Sedna
- Quaoar
- Orcus
- 2007 OR10
Brown, estimates that there are many more, and listed 390 candidates in a 2011 publication.
What else can I help you with?
Is there such a planet called Eris?
No. Planet X was a provisional name for a planet believed to exist beyond the orbit of Neptune based on a slight anomaly in its orbit. It was later realized that the anomaly was due to a miscalculation of the mass of Uranus.
Is Eris a planet in the milky way galaxy?
Eris is not a planet in the Milky Way galaxy; it is a dwarf planet located in the outer solar system. It is the most massive dwarf planet known to exist and is part of the Kuiper Belt, a region beyond Neptune that is home to many icy bodies.
Does Neptune exist?
Yes. Neptune is the outermost planet in the solar system.
Where is life known to exist in the solar system?
planet earth
What is the smallest planet in the galaxy?
The smallest planet in our solar system is mercury. It's the smallest known planet in our galaxy, since we would not be able to see one that small in any other far off systems. smaller planets could exist, would they still have to fulfil the same criteria? Ceres, a dwarf planet is only 900km in diameter. This is about the limit, much smaller than this and the planet would struggle to hold a spherical shape.
Is the dwarf planet zena considered a planet in the solar system?
Zena is not classified as anything - as it does not exist.
What would classify Pluto as a planet?
It isn't a planet. It doesn't exist in the solar system anymore. As a dwarf planet, but not as a proper planet.

No. Planet X was a provisional name for a planet believed to exist beyond the orbit of Neptune based on a slight anomaly in its orbit. It was later realized that the anomaly was due to a miscalculation of the mass of Uranus.

Does Neptune exist?
Yes. Neptune is the outermost planet in the solar system.
Where is life known to exist in the solar system?
planet earth
Is Pluto the only dwarf planet in the Milky Way?
No. There are four other objects in out solar system classified as dwarf planets: Ceres, Haumea, Makemake, and Eris. Several others are being considered for this classification. Dwarf planets are too small for us to detect them in other solar systems with current technology, but they almost certainly exist.
Why is there 8 planets?
In 2006 the international astronomical union changed the definition of what a planet was. This meant that Pluto no longer met the definition of what a classic planet was and it was demoted to a dwarf planet status instead.
What is the smallest planet in the galaxy?
The smallest planet in our solar system is mercury. It's the smallest known planet in our galaxy, since we would not be able to see one that small in any other far off systems. smaller planets could exist, would they still have to fulfil the same criteria? Ceres, a dwarf planet is only 900km in diameter. This is about the limit, much smaller than this and the planet would struggle to hold a spherical shape.
Is Eris a real planet?
Yes and no. It does exist but it's classified as a dwarf planet.
Is Planet X bigger than Jupiter?
Planet X has not been confirmed to exist, so its size is unknown. Jupiter is the largest planet in our solar system, with a radius of about 69,911 km.
What is the radius of a white dwarf with a mass of 1.5 solar units?
Such a white dwarf could not exist. Above 1.4 solar masses a white dwarf will collapse to form a neutron star.
