With a radius of about 722 miles (1,163 kilometers), Eris is
about 1/5 the radius of Earth
. Eris, like Pluto, is a little smaller than Earth’s Moon. If the Earth were the size of a nickel, Eris would be about as big as a popcorn kernel.
How big is Pluto vs Eris?
In addition to measuring Eris’ size, researchers were also able to determine its shape, size and mass. The observations helped scientists determine that Eris’ diameter is 1,445 miles (2,326 kilometers), give or take 7 miles (12 km). That makes
it slightly smaller than Pluto
.
What is Eris mass compared to Earth?
Eris has been measured at 2,326 ± 12 kilometers (1,445 ± 7 mi) in diameter. Its mass is
0.27 percent that of the Earth
and 127 percent that of dwarf planet Pluto, though Pluto is slightly larger by volume. As Eris orbits the Sun, it completes one rotation every 25.9 hours, making its day length similar to Earth’s.
How many Eris can fit in the Earth?

How cold is Eris?
It has a highly eccentric orbit around the Sun, which causes its surface temperature to vary from
-217 degrees Celsius to -243 degrees Celsius
. Observations of Eris have led scientists to believe that it has frozen methane on its surface. At 2400 kilometers in diameter, Eris is slightly larger than Pluto.
