Scientists Confirm No Evidence Of Planet X In 75% Of Suspected Sky Regions Following Extensive Survey

Recent research by American planetary scientists has largely dismissed the possibility of a ninth planet, often called "Planet X," in 75% of the sky regions where it was once thought to exist. This conclusion follows a comprehensive survey of the outer solar system using the PAN-STARRS1 telescope in Hawaii, with findings shared on arXiv.org.

The study, led by Matthew Holman from the Harvard-Smithsonian Center for Astrophysics, represents one of the most extensive searches for distant planet-sized bodies. During this investigation, 692 small celestial objects were identified, including 23 dwarf planets and 109 newly discovered entities.

The PAN-STARRS1 telescope, initially designed to spot fast-moving objects like asteroids and comets, was employed to search for slow-moving planetary bodies. Researchers developed a unique algorithm to combine multiple images of identical sky regions captured between 2009 and 2017. By referencing known asteroids with precise orbits within these images, they accurately tracked distant objects located 80 astronomical units (AU) or more from the Sun.

Despite these efforts, no evidence of Planet X or any other large body was found. The search significantly narrowed down potential locations for such a planet to a small unexplored region near the Milky Way galaxy's plane. This area has not been thoroughly examined by the telescope yet and requires further study.

The hypothesis of Planet X gained traction in 2016 when Konstantin Batygin and Michael Brown presented indirect evidence suggesting its existence. They proposed that a ninth planet, possibly similar in size to Neptune or Uranus, might orbit at least 100 billion kilometres (around 670 AU) from the Sun.

Although numerous searches have been conducted since then, this elusive planet remains unobserved. This lack of direct observation has led some astronomers to question its existence and consider alternative explanations for gravitational effects noted in the outer solar system.

Future Prospects

None of the analysed images showed signs of Planet X. This effectively limits its possible location to an unexplored region near the Milky Way's plane. Further investigation is needed as this area has not been surveyed in detail by current telescopes.

The ongoing quest to find Planet X continues to intrigue scientists. While recent findings have narrowed down potential locations, further exploration is necessary to confirm or refute its existence conclusively.
