How can humanity use the developing Lunar Gateway as an appropriate starting point for advancing human space exploration beyond the moon? This is what a recent study presented at the 56th Lunar and ...

The discovery challenges the Planet Nine hypothesis, which suggests a massive, unseen planet is influencing the orbits of distant TNOs. While most extreme TNOs show a clustered pattern that supports ...

OF201 spends only 1% of its orbital time close enough to us to be detectable. The presence of this single object suggests ...

OF201 is incredibly lightweight on a cosmic scale. Scientists estimate its mass is about 20,000 times less than Earth’s and ...

American scientists believe they have discovered a new dwarf planet at the edge of the solar system. Named OF201, this object ...

Scientists have identified an object about 435 miles (700 km) wide inhabiting the frigid outer reaches of our solar system that might qualify as a ...

The TNO, which are described as minor planets that orbit the sun at a greater distance than Neptune, were found on the edge ...

Scientists have discovered a colossal object approximately 435 miles wide in the frigid outer reaches of our solar system, ...

OF201, a possible dwarf planet with a 25,000-year orbit, challenging theories about Planet Nine and the solar system’s edge.
