A new object discovered at the edge of the solar system, named 2023 KQ14, nicknamed "Ammonite", is making astronomers question the early past of the Thai Duong system. This is the fourth member of the sednoid group - an extremely distant object located far from the major planets.
Ammonite is not an island or satellite like Diem Vuong, but is grouped with Sedna, Biden and Leleākūhonua. Her center of mass has the farthest point from the sun to 342 astronomical units (A Us), more than 11 times the distance from the star Hai Vuong. With a diameter of 220 to 380 km, Ammonite is much smaller than the star Lam Vuong.
This celestial body took about 4,000 years to complete a circle around the sun. Supercomputers show that the trajectory of Ammonite has been stable for more than 4.2 billion years. These characteristics make experts believe that Ammonite is an "aresistent fossil" from the formation of the Pacific Ocean.
Ammonite was discovered in March 2023 thanks to Japan's Subaru Galaxy headset in the FOSSIL project. By July 2024, the trajectory of this object was more accurately determined with the support of the Canada - France - Hawaii Galaxy.
The discovery of Ammonite helps reveal that a strange event occurred in the early days of the solar system, such as the appearance of an unknown planet or a star passing by, changing the trajectories of celestial bodies.
