What is the density of Eris?
2.52 grams per cm3
It was found to be 27% heavier than Pluto [4]. Combined with its diameter, this provided Eris’s density, estimated at 2.52 grams per cm3 [5]. “This density means that Eris is probably a large rocky body covered in a relatively thin mantle of ice,” comments Emmanuel Jehin, who contributed to the study [6].

Eris/Gravity
Though its gravity is weak compared to earth, Eris has the strongest gravity out of all the dwarf planets: 0.82 m/s².
Why was Eris named Eris?
Namesake. Originally designated 2003 UB313 – and nicknamed for the television warrior Xena by its discovery team – Eris is named for the ancient Greek goddess of discord and strife. The name fits since Eris remains at the center of a scientific debate about the definition of a planet.
What is the solar distance of Eris?
From an average distance of 6,289,000,000 miles (10,125,000,000 kilometers), Eris is about 68 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth.
What is the temperature of Eris?
Eris is one of the distant known bodies in the solar system, with the exception of a few long-period comets . Its surface temperature is between 23 and 24 kelvins (-250 to -249 degrees Celsius).
Is Eris a dwarf planet?
Eris (minor-planet designation 136199 Eris) is the most massive and second-largest (by volume) dwarf planet (and plutoid) known in the Solar System.
Does Eris have water?
Models of internal heating via radioactive decay suggest that Eris could have an internal ocean of liquid water at the mantle-core boundary.
