The surface is made up of Methane ice similar to that of Pluto
Methane, Ice, and Rock
The surface pressure on the dwarf planet Eris is not currently known, as there have been no direct measurements taken. Eris is a distant world in our solar system, and its characteristics are still being studied by astronomers.
Probably. Eris is too far away for us to make out and of the features on its surface and we have not sent any probes there.
Eris, the dwarf planet, has a surface temperature of around -238 degrees Celsius (-396 degrees Fahrenheit) due to its distance from the Sun.

Eris is a "dwarf planet", and does not have enough gravity to make the surface round, or to clear other objects near to it.
hard as a rock because it is made of rock.
Eris has an average surface temperature of around -235 degrees Celsius, which is significantly colder than Earth's average surface temperature of around 15 degrees Celsius. Eris is much farther from the Sun than Earth, contributing to its extreme cold temperatures.

None. It is too cold to have any gasses. The surface appears to be methane frozen into solid methane.
