Astronomers have discovered a rare object, 2020 VN40, in the outer solar system that moves in a unique 10:1 resonance with Neptune, challenging existing ideas about the movement and evolution of distant solar system objects. This discovery, along with others like 'Ammonite,' provides new insights into the gravitational influences and history of our solar system's outer regions.
Scientists have discovered evidence of large objects beyond the outermost perimeter of the Kuiper Belt, suggesting that the belt is deeper than previously thought. The objects, detected by NASA's New Horizons spacecraft, could be located beyond 60 astronomical units (AU) from the solar system's center, indicating the possibility of a second belt. However, the findings are preliminary and further research is needed to confirm their existence. Telescopes have yet to detect objects beyond the Kuiper Belt's limits, but dimming in stars observed by the Hubble Space Telescope suggests the presence of undiscovered Kuiper Belt objects.
