Penemuan sejumlah planet baru ini adalah hasil terkini dari proyek exoALMA, sebuah kerjasama internasional yang menggunakan instrumen Atacama Large Millimeter.

When astronomers found a large world farther out than Pluto, it became one of the final nails in the coffin of our ninth planet.

January 5, 2005, is an astronomical anniversary that is not really marked but should be. It saw the discovery of dwarf planet Eris and how those very observations led to a new way to describe the ...

On Jan. 5, 2005, Eris was discovered. It was considered the largest known dwarf planet in the solar system until a year later when Pluto was downgraded from being a planet.

The dwarf planets in question, Eris and Makemake, are both found in the Kuiper Belt past Neptune's orbit and are far from the Sun's warmth, similar to fellow dwarf planet Pluto.

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

Pluto's 'almost twin' dwarf planet Eris has a rocky core blanketed by an icy shell, which appears to be flexing slowly.

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.
