Astronomers have discovered a new member of a rare and mysterious class of solar system objects known as sednoids - a subset of extreme trans-Neptunian objects (ETNOs) with exceptionally distant, ...

The celestial body's unusual orbit “implies that something extraordinary occurred" in the early days of the solar system—and ...

Typically, telescopes are synonymous with bringing far-off objects close, but the newest member of the solar system was ...

KQ14, nicknamed “Ammonite”, was discovered using the Subaru Telescope and is a highly elliptical object with a perihelion and aphelion that places it beyond the ...

For reference, Pluto’s average distance from the Sun is about 40 AU, so 2023 KQ14 is quite distant. At 23.4 billion miles (37 ...

Astronomers using the Subaru Telescope have discovered a strange new body in a weird orbit at the edge of the solar system, ...

A tiny object far beyond Pluto, newly discovered by the Subaru Telescope, could reshape our understanding of the early Solar System. Named 2023 KQ14, this rare “sednoid” follows an unusual orbit that ...

The discovery was made by astronomers using the Subaru Telescope, which is situated atop a dormant volcano in Hawaii.

The “new world” was found as part of the survey project FOSSIL (Formation of the Outer Solar System: An Icy Legacy), hence its nickname, Ammonite. An ammonite is a fossil of a cephalopod that died out ...

The new sednoid, called 2012 VP113, was discovered by Chadwick A. Trujillo and Scott Sheppard of the Gemini Observatory in Hawaii. Its closest approach to the sun is 7.4 billion miles, ...

The sednoid is estimated to be between 136 and 236 miles (220 and 380 kilometers) wide. That makes it 45 times wider than the height of Mount Everest. You may like ...
