Eris and Makemake, two dwarf planets beyond Neptune, may be host to geothermal activity and therefore be more habitable than was once thought.

Eris' surface was also found to be extremely reflective, bouncing back 96% of the light that hits it. That makes Eris one of the most reflective bodies in the solar system, roughly on par with ...

Eris appears to have a very reflective surface, suggesting that it is uniformly covered in a thin layer of ice, probably a frozen atmosphere.

The new COVID variant Eris is on the rise. Here's everything you need to know about it and how to protect yourself from it.

Webb telescope spots hints that Eris, Makemake are geologically active Webb measured isotopes at the edge of the Solar System, hinting at chemistry.

Eris and Makemake—two icy worlds beyond the orbit of Pluto—have seemingly fresh methane on their surface, a sign of unexpectedly hot interiors ...

University of California, Santa Cruz Professor of Planetary Sciences Francis Nimmo recently co-authored a Science Advances paper about the internal structure of the dwarf planet Eris.

The U.S. is seeing a summer uptick in COVID-19, due mostly to the spread of the highly contagious Eris subvariant.

EG.5.1, nicknamed Eris, is an Omicron subvariant currently spreading through the U.S. and U.K. Here's what you should know about the new COVID strain.

It's this that gives Eris its fluid, and yet not fluid, surface composition, like a snowball in a constant state of melting without ever becoming melted.
