Previous direct imaging of Eris showed that its surface composition includes methane and probably nitrogen. Due to the body’s brightness, astronomers think those chemicals exist as ice—leading to the idea of a frozen atmosphere.The occultation indicated that there is no appreciable atmosphere on Eris, meaning it’s at least 1/10,000 that of Pluto’s. That, combined with the high surface brightness of Eris, suggests that it has a recently collapsed atmosphere—that is, an atmosphere that has frozen onto the surface.This very thick layer of mostly water ice is not to be confused with the very thin layer of frozen atmosphere on Eris’s surface that makes it so reflective.

What is Eris climate?
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.
Is Eris rocky or gas?
Eris is so far from the Sun that its atmosphere sometimes freezes due to lack of sunlight. It thaws as it gets closer to the Sun’s heat over the course of its 557-year orbital period. Scientists believe that the surface of Eris is rocky. This is similar to the surface found on Pluto.

Who Killed Pluto as a planet?
Mike Brown is best known as the man who killed Pluto. The Caltech astronomer led the team that discovered Eris, a rocky world circling the sun far beyond Pluto, in 2005. Eris was thought to be larger than Pluto, and the find helped spur astronomers to redefine just what a planet is.
Does it snow on Eris?
Nitrogenice turns into a gas at cooler temperatures and so there would be more nitrogengas in the atmosphere compared with methane. Then, at the shaded pole, alsocalled the winter hemisphere, the gases would condense into snow-like ordew-like material that would fall onto Eris’ surface as nitrogen ice.
