Where are the 5 dwarf planets located?
There are 5 Dwarf planets – Ceres, Pluto, Haumea, Makemake & Eris. All of these planets are located in the outer solar system; that is, except for Ceres, which is actually located in the asteroid belt. However, this is only the dwarf planets that we know of, and that are classified as a “dwarf planet”.
Why is Pluto now called a dwarf planet?
Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”

How many dwarf planets are there in our Solar System?
The solar system’s erratic ninth planet, Pluto, was assigned to the new “dwarf planet” category along with four other bodies, all tinier than Earth’s moon. Some astronomers expect there may be as many as 50 dwarf planets in the solar system.
Which is the shortest day of the dwarf planets?
Haumea rotates very rapidly and has the shortest day of all the dwarf planets, only 3.9 hours. Orbiting 43.1 times farther from the sun than Earth does, Haumea takes nearly 282 Earth years to complete one orbit.
How big is the dwarf planet Eris compared to Pluto?
The solar system’s erratic ninth planet, Pluto, was assigned to the new “ dwarf planet ” category along with four other bodies, all tinier than Earth’s moon. Some astronomers expect there may be as many as 50 dwarf planets in the solar system. Eris, the largest dwarf planet, is only slightly bigger than Pluto, at 1,445 miles in diameter (2,326 km).
Are there any rings around the dwarf planet Pluto?
They all spin and don’t keep the same face towards Pluto. There are no known rings around Pluto. Dwarf planet Pluto is a member of a group of objects that orbit in a disc-like zone beyond the orbit of Neptune called the Kuiper Belt.
