Methane, Ice, and Rock
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.
Scientists use telescopes, specifically large ground-based telescopes and space telescopes like the Hubble Space Telescope, to study Eris. These telescopes allow them to observe Eris' size, shape, surface features, and composition.
The surface is made up of Methane ice similar to that of Pluto
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.
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.
Yes, there is a dwarf planet called Eris. It is one of the largest known dwarf planets in our solar system and was discovered in 2005. Eris is similar in size to Pluto and is located in the Kuiper Belt, beyond the orbit of Neptune.
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.
