Recent astronomical discoveries suggest that our solar system may be much larger than previously thought, and that there may be a second Kuiper Belt in addition to the one we know. Astronomers using the powerful Subaru Telescope have discovered 11 new objects orbiting outside the known Kuiper Belt, suggesting the existence of a second Kuiper Belt, tentatively named “Kuiper Belt 2.”
What is the Kuiper Belt?
The Kuiper Belt is a distant region of the Solar System beyond Neptune that is approximately 33 to 55 astronomical units (AU) wide. The Kuiper Belt contains icy bodies and comets orbiting the Sun and was the primary target of NASA’s New Horizons mission, which famously explored Pluto in 2015.
Beyond the known Kuiper Belt lies a vast, unexplored region of space where scientists now believe even more mysterious objects may reside.
New discoveries beyond the Kuiper Belt
Since 2020, scientists have discovered 239 Kuiper Belt Objects using Subaru’s Super Super Camera (HSC). However, the most significant discoveries were 11 objects located between 70 and 90 AU from the Sun, suggesting the existence of a second, more distant Kuiper Belt. This new belt may extend to 13.5 billion kilometers (8.4 billion miles) from the Sun.
Notably, there is a gap between 55 and 70 AU where no objects have been detected, further supporting the idea of a second distinct belt.
Implications for our understanding of the solar system
The discovery could reshape our understanding of how our solar system formed. For years, scientists have believed that the Kuiper Belt was unusually small compared to similar belts in other planetary systems. However, the discovery of Kuiper Belt 2 suggests that our solar system may be more typical, with a primordial nebula that was larger than originally thought.
The Kuiper Belt 2 discovery is still under investigation, but it hints at the possibility of more dwarf planets and even the long-theorized Planet Nine. As astronomers continue to observe these distant objects, we may find more surprises in the outer reaches of our solar system.
