Astronomers at the Vera C. Rubin Observatory in Chile announced detection of an object, provisionally named 2026 ED138, orbiting about 4.3 billion miles from the Sun, roughly 46 times Earth's distance. Early estimates put its diameter between 370 and 930 miles, and its orbit is tilted 25 degrees from the plane most planets follow. If confirmed, it would be the first new dwarf planet classified since the International Astronomical Union set the category's rules in 2006.

The International Astronomical Union has officially approved asteroid (14331) Alyankovic, honoring musical satirist 'Weird Al' Yankovic, alongside another asteroid named for Tom Lehrer, the mathematician and satirical songwriter who died last year at 97. The naming effort was led by planetary scientist Allison McGraw with support from several scientists including astrophysicist Steve Desch, Smithsonian curator Tim McCoy, and Spacewatch program leader Melissa Brucker.

Two decades after the International Astronomical Union voted in 2006 to reclassify Pluto as a dwarf planet, a vocal group of scientists, historians and enthusiasts continue to push back against that decision. Critics like Philip Metzger of the University of Central Florida argue the IAU's planetary definition is scientifically unworkable, while others such as writer Laurel Kornfeld have campaigned against the ruling since the day it was announced. The dispute remains largely an American phenomenon, tied partly to national pride since Pluto was discovered by a US astronomer in 1930.

It has been two decades since the International Astronomical Union voted in August 2006 to strip Pluto of its planetary status, reclassifying it as a dwarf planet after astronomers discovered a similarly sized object, later named Eris, in 2005. The decision remains contentious, with figures like NASA Administrator Jared Isaacman and actor William Shatner recently arguing Pluto deserves to be called a planet again.
