Scientists have identified a new minor planet beyond Pluto , enhancing our knowledge of the solar system 's outer boundaries. The celestial body, designated as 2017 OF201 , ranks among the largest distant objects ever detected, providing fresh insights into the Kuiper Belt and the remote regions of our planetary International Astronomical Union's Minor Planet Center officially recognised 2017 OF201 after its detection in archived telescope data. The object's remarkable characteristics include its substantial size and distinctive orbital path. Its estimated diameter ranges from 470 to 820 kilometres (approximately 290 to 510 miles), placing it amongst known dwarf planets and substantial asteroids like highly eccentric orbit varies between 45 astronomical units (AU) from the Sun - approximately 45 times Earth's distance from the Sun - to a remarkable 838 AU at its apex. For context, Neptune orbits at about 30 AU. This extensive elliptical trajectory classifies 2017 OF201 as an extreme trans-Neptunian object (ETNO), belonging to a category of bodies residing in the solar system's furthest Kuiper Belt, home to Pluto and other frozen bodies, remains an enigmatic region containing remnants from the solar system's formation over 4.5 billion years ago. The discovery of 2017 OF201 assists astronomers in understanding the origin, evolution, and formation of these objects, providing data about the solar system's early discovery of 2017 OF201 contributes to ongoing investigations regarding a potential ninth planet beyond Neptune. The theoretical "Planet Nine" would exert gravitational influence over several ETNOs' orbits. While 2017 OF201's trajectory doesn't precisely align with Planet Nine predictions, each newly discovered outer solar system object provides crucial data for refining astronomical models and the Planet Nine theory, studying distant objects like 2017 OF201 enhances understanding of the solar system's outer structure and mechanics. These objects serve as preserved evidence of planetary movements, impacts, and other historical facilities like the Vera C. Rubin Observatory will accelerate the identification of distant solar system objects, improving our understanding of these remote areas. Current research continues to illuminate the solar system's boundaries and the principles governing our cosmic 2017 OF201 represents a significant discovery among trans-Neptunian objects. It addresses current knowledge gaps while extending our understanding of the solar system's reach, establishing foundations for future astronomical research.
