List of possible dwarf planets
The number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt [1] and over 10,000 in the region beyond. [2] However, consideration of the surprisingly low densities of many large trans-Neptunian objects, as well as spectroscopic analysis of their surfaces, suggests that the number of dwarf planets may be much lower,
Dwarf Planets
Poor Pluto. As if this faraway frozen ball''s long journey around the sun—a squashed trajectory that takes 248 years—wasn''t strange enough, Pluto''s story took an even stranger turn in 2006, when astronomers stripped it of its status as our ninth planet. But Pluto''s loss was actually a gain for wannabe astronauts. Suddenly, the solar system offered new "planets" to explore.

Solar System
The Solar System [d] is the gravitationally bound system of the Sun and the objects that orbit it. [11] It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its
6 FAQs about [Dwarf planets in our solar system]
How many dwarf planets are there?
So far, the IAU has only recognized five dwarf planets. In order of distance from the Sun they are: Ceres, Pluto, Haumea, Makemake, and Eris. But the IAU says there may be many more dwarf planets – perhaps more than a hundred – waiting to be discovered. Ceres is the only dwarf planet located in the inner solar system.
What makes a planet a dwarf planet?
The International Astronomical Union defines a planet as being in orbit around the sun, has enough gravity to pull its mass into a rounded shape (hydrostatic equilibrium), and has cleared its orbit of other, smaller objects. This last criterion is the point at which planets and dwarf planets differ.
Which dwarf planet is located in the inner Solar System?
Ceres is the only dwarf planet located in the inner solar system. Pluto was long considered our solar system's ninth planet. Haumea is one of the fastest rotating large objects in our solar system. Makemake is the second-brightest object in the Kuiper Belt. Eris is one of the largest known dwarf planets in our solar system.
Which Solar System bodies are dwarf planets?
But those aren't the only ones. Other solar system bodies that are possibly dwarf planets include Sedna and Quaoar, small worlds far beyond Pluto's orbit, and 2012 VP113, an object that is thought to have one of the most distant orbits found beyond the known edge of our solar system.
What does a dwarf planet do?
According to the IAU, a planet must do three things: Orbit its host star (In our solar system that’s the Sun). Be mostly round. Dwarf planets like Pluto were defined as objects that orbit the Sun, and are nearly round, but have not been able to clear their orbit of debris. So far, the IAU has only recognized five dwarf planets.
Which planets are most likely to be a dwarf planet?
Planetary geologists are therefore particularly interested in them. Astronomers are in general agreement that at least the nine largest candidates are dwarf planets – in rough order of size, Pluto, Eris, Haumea, Makemake, Gonggong, Quaoar, Ceres, Orcus, and Sedna.
