Astronomers in Japan have seen a distant object revolving beyond the Neptune, indicating an extraordinary event that occurred during the early years of the solar system.

Astronomers used Subaru telescope, which was located above a passive volcano in Hawaii to search. He revolted with a small object at the farthest distance of 252 AU from the Sun, with an astronomical unit equal to the average distance between the Sun and the Earth. Scientists gave it a formal designation 2023 KQ14 and after a extinct group of maritime animals gave it a nickname of Ammonit – a node to its position as the extreme remains of the early solar system.

For reference, the average distance from the Sun to Pluto is about 40 AUs, so 2023 KQ14 is far away. Away from 23.4 billion miles (37.7 billion kilometers), it takes about 34 hours to reach the Earth in the light that reflects amonite.

Search, Published Nature is a symbol of the fourth detection of a “sednoid” on Tuesday in the astronomy. The distant group, Trans-Neptunian items have extremely long classes that are spread over the back of the cuper belt. Unlike other items, which revolve around the rear sun of Neptune, sednoids are separated from the vast planet, meaning that they are not affected by its gravitational region. In 2003, astronomers discovered the first Sednoid called Sedna.

Astronomers first discovered Ammonit through Subaru’s survey project, fossil (formation of external solar system: an icy heritage) in 2023. Follow-up observation in July 2024 confirmed the search, using the Canada-France-HAVI telescope, disclosing the orbit of the object. It was also seen in the collection images taken in 2021 and 2014, allowing astronomers to simulate their class with greater accuracy.

Using computer simulation, researchers behind the search show that Ammonit has maintained a stable class for at least 4.5 billion years. On its nearest approach to the Sun, it comes within 66 AUS from the star. Unlike its sedanoid counterparts, Ammonite currently follows a different orbit. However, simulation indicated that all four known sednoids classes were very similar about 4.2 billion years ago. It questions the existence of nine in theory.

Sednoids are one of the major pieces of evidence behind the long -held principle that revolve around the Sun beyond a massive ninth planet Neptune. The group of small objects follows a strangely alignment, long orbit, which cannot be explained based on the gravitational effect of the known planets of the solar system, suggesting that a ninth, ignorant planet may be tagging on the cedonoids.

The fact that the current class of Ammonite does not align with the other three sedonoids, reduces the possibility of the planet of nine hypothesis, “Yukun Huang, a researcher at Japan’s national astronomical observatory, carried out the simulation of the class of Ammonite, said in one, in one, it is said in one. statement“It is possible that a planet was once present in the solar system, but later it was thrown out, which we look at unusual classes today.”

Ammonite is estimated between 136 and 236 miles wide (220 and 380 km). However small, its presence is a sign of something very large in the game. “Ammonite was found in an area where Neptune’s gravity has little effect. The presence of long classes and distance of large perihelians in this region means that something was extraordinary during the ancient era, when Ammonit was formed,” Fumy Yoshida, a planetary, a planetary scientist and new study said in a statement. “It is important to understand the complete history of the solar system and to understand the orbital properties of these unique, distant objects.”
