What this story says

  • An icy object, designated 2026 ED138, has been discovered beyond Pluto by scientists using a telescope in Chile.
  • The object's diameter is estimated to be between 600 and 1,500 kilometres.
  • Further observations are required to confirm if 2026 ED138 meets the criteria for classification as a dwarf planet.
  • If classified as a dwarf planet, 2026 ED138 would join Pluto, Ceres, Eris, Haumea, and Makemake.

Scientists have identified an icy object, named 2026 ED138, orbiting the sun in a region beyond Pluto. The discovery was made using a telescope located in Chile. Initial estimates place the object's diameter between 600 and 1,500 kilometres. Further observations are necessary to determine if 2026 ED138 will be classified as a dwarf planet.

If classified as a dwarf planet, 2026 ED138 would become the sixth such celestial body in our solar system. The current list of known dwarf planets includes Pluto, Ceres, Eris, Haumea, and Makemake. The object's orbital path is approximately 46 times further from the sun than Earth's.

Object size estimates

Reports agree that the object 2026 ED138 is estimated to be between 600 and 1,500 kilometres in diameter. IMLebanon reported this range, stating it is "about 600 to 1,500 kilometres in diameter." The Hindu Business Line, WCVB, WMUR, Koco News5, WTAE, KCCI, WISN, KETV, WPTZ, KMBC, WBAL-TV, WMTW, WVTM, KOAT, WAPT, WPBF, WGAL, KSBW, WJCL, KHBS, MOR-TV, The Paintsville Herald, and Appalachian News-Express all carried this information without providing specific wording on the estimate.

What the coverage left out

None of the centre or right-rated digests mention the estimated distance of the object's orbit from the sun, which was reported as approximately 46 times further than Earth's orbit in the unrated IMLebanon digest.

Still developing. We have re-checked which outlets are covering this 2 times, most recently on 29 Oct 2026, 00:45, and will add the sides that appear.

How each side covered it

Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.

Left

14 rated outlets

  • Two left‑rated outlets gave a size estimate for the object. CBC and Delo reported that the icy body, named 2026 ED138, was discovered with the Vera C. Rubin Observatory in Chile and orbits roughly 46 astronomical units from the Sun. Both said its diameter is estimated between about 600 and 1 500 kilometres, placing it among the largest dwarf‑planet candidates.
  • CBC quoted astrophysicist Matt Holman of the Harvard‑Smithsonian Center for Astrophysics, who first identified the candidate. Delo included remarks from Holman and from astronomer Mario Jurić of the University of Washington, with Jurić describing the find as a once‑per‑generation event. No direct quotations appear in the digests.
  • The digests omitted methodological details such as the data‑mining program used by Holman and Kevin Napier, and they did not mention the archival image search that extended observations back to 2016. They also left out the reference to NASA’s upcoming Roman Space Telescope that appears in CBC’s report.

  • Twenty-two centre-rated digests reported the discovery of an icy object beyond Pluto that could be a new dwarf planet. These digests stated that astronomers used the world's largest telescope to spot the object. They also noted that further observations are needed to determine its dwarf planet status. The Paintsville Herald and Appalachian News-Express digests mentioned that the object would join the five other known dwarf planets: Pluto, Ceres, Eris, Haumea, and Makemake.

  • The single right-rated digest reported that scientists spotted icy object 2026 ED138 beyond Pluto using Chile's Rubin Observatory. It stated that further observations will determine whether it qualifies as a dwarf planet.

Questions about this coverage

How did the left and right cover Astronomers Discover Icy Object 2026 ED138 Beyond Pluto?
Of the 89 outlets on this story carrying a published leaning rating, 16% are rated left, 70% are rated centre, 14% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 129. The sections above set out what each side emphasised, in its own terms.
Is Astronomers Discover Icy Object 2026 ED138 Beyond Pluto left or right?
The story itself is neither. What can be counted is who has covered it, and 70% of the 89 rated outlets on it are rated centre — so far this is a story carried mostly by the centre. Coverage is still arriving and that can change, which is why the figure is dated rather than fixed.
Is the coverage of Astronomers Discover Icy Object 2026 ED138 Beyond Pluto biased?
Astronomers Discover Icy Object 2026 ED138 Beyond Pluto is one event reported by 129 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which outlets covered Astronomers Discover Icy Object 2026 ED138 Beyond Pluto?
129 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
What is 2026 ED138?
2026 ED138 is an icy object discovered orbiting the sun beyond Pluto. Scientists are conducting further observations to determine if it meets the criteria to be classified as a dwarf planet.
How large is 2026 ED138?
The object 2026 ED138 is estimated to be between 600 and 1,500 kilometres in diameter. This size range is based on initial observations made by scientists using a telescope in Chile.
What are the known dwarf planets?
The known dwarf planets in our solar system are Pluto, Ceres, Eris, Haumea, and Makemake. If 2026 ED138 is classified as a dwarf planet, it would join this list.
