Pluto
Eris - a dwarf planet.
No, it is not. Mercury's radius is more than twice as large.
No. scientists have found dozens of planets about the same size as Eris and Pluto. I think they should just be Dwarf planets.
Eris is an OUTER planet. The only inner planets are mercury, venus, earth and mars. An outer planet is not related to the size of the planet but rather the distance from the sun.
A planet the same size as Pluto would likely be classified as a dwarf planet, given the criteria set by the International Astronomical Union. It would have a diameter of about 2,377 kilometers and an orbital path beyond Neptune in the Kuiper Belt.
It is a moon of the dwarf planet Pluto. They are so nearly the same size it could almost be called a double planet system
Eris is a spherical object that is 2326 kilometers across on average, which makes it slightly smaller than Pluto.
size, name, type, age and colour
Yes Mercury (smallest), Mars and Venus (nearly the same size asEarth).
Venus, hands down. Venus is very nearly the same size as Earth. Jupiter is several times larger.
There is no planet that has the same size moon as the planet. This is only possible if Pluto was still a planet.
The second dwarf planet to be officially recognized by the International Astronomical Union (IAU) was Eris, which was designated as a dwarf planet in 2006. Eris is located in the scattered disc region of the solar system and is known for its size, which is similar to that of Pluto. Its discovery in 2005 prompted a re-evaluation of the definition of planets, ultimately leading to the classification of both Pluto and Eris as dwarf planets.
