A new study suggests that our solar system can hide another mysterious world yet. Researchers believe that an Earth -shaped planet, nickname planet Y, beyond Neptune, can be microscopically away from tugging on icy objects on the edge of the solar system, New scientist Informed
Research published on Preprint Server Arxiv, The Institute for Advanced Study with Astrophizist Scott Trade, Amir Siraj of Princeton University and Christopher F. Comes from chiba. Their work focuses on the unexplained orbital inclination seen in the cuper belt- a distant area filled with icy body, including the dwarf planet Pluto.
Planet Y vs planet nine
Scientists have long estimated the planet nine- a vast world estimates that the mass of the Earth is 10 times more and revolves around 300 times away from the Sun. Planet Y, however, is the principle for being very small, somewhere in the shape of mercury and earth, and planet is located closer than nine.
The team suggests that the planet’s gravity may explain why some cuper belt objects appear to be bent at an unusual 15-degree angle, rather to align neither with a flat orbital aircraft of the solar system.
Siraj estimates that only 2-4% chance that this discovery is a statistical coincidence- about the same obstacles that gave weight to the first planet nine theory. By re -shaping our understanding of the architecture of the solar system, both Planet Nine and Planet Y can be present together.
Where did the planet Y come from?
Jonty Horner, an astronomer at the University of Southern Queensland, commented on the study, saying the idea is “admirable.” He said that the outer solar system is largely unexplained and suggested that the planet may not be Y where it is now. Instead, it may have been pushed outward during the early days of the formation of planets, when giant planets were still transferred to stable classes.
Rubin observatory can answer
The mystery may be resolved soon. The upcoming Vera c in Chile. The Rubin Observatory, through the space and time (LSST) of its ambitious heritage survey, is expected to provide deep insight into the cuper belt. Researchers say that if the planet Y is located within the survey limit of the Y Poshala, it can eventually be detected.
The authors wrote, “If such a body exists, but is not discovered by LSST due to its on-a-sight location, LSST will still reveal more about the unusual orbital inclination of the cuper belt,” the authors wrote.
For now, Planet Y remains fictional- but with the arrival of new telescopes online, hunting for the world hidden beyond Neptune is entering an exciting phase.
