Eris has an average surface temperature of 42.5 kelvin which is roughly -230C (-383F) so quite cold.
Neptune(If you include dwarf planets it is Eris)
The temperature on the Dwarf Planet Eris is below 120 degrees Celcius.
The dwarf planet Eris has a minimum surface temperature of 30oK (-405.67oF, -243.15oC), a mean temperature of 42.5oK (-383.17oF, -230.65oC), and a maximum temperature of 55oK (-360.67oF, -218.15oC).
in the eris is hot and cold combine and the rest the cold and hot are seprite :D

Eris is a spherical object that is 2326 kilometers across on average, which makes it slightly smaller than Pluto.
Pluto's temperature is around 43 K. For comparison, the temperature on Earth is somewhere around 300 K. Pluto's temperature should vary quite a bit, depending on its distance from the Sun, since its orbit is fairly excentric.
Pluto is closer to the sun on average than Eris is, but both have probably existed for about the same amount of time.
Eris is 97 astronomical units away from the sun. ( an astronomical unit is the average distance between Earth and the Sun)
The average temperature is here. The average temperature is here.
About 30 Kelvin, 30° above absolute zero (or -243°C).
