For the dwarf planet candidate, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical Planet Nine.

The discovery of a Saturn-sized gas giant orbiting a small red dwarf is urging astronomers to reconsider their theories of ...

Some scientists think they discovered a new dwarf planet at the edge of the solar system, so far away that it takes around 25,000 years to complete one orbit around the sun. Astrophysicist Dr. Paul ...

Astronomers have spotted a cosmic mismatch that has left them perplexed - a really big planet orbiting a really small star.

A small red dwarf star, TOI-6894, is defying astronomers' expectations by having a gas giant planet in its orbit.

With its low density and unusually cool, methane-rich atmosphere, this planet offers a rare window into giant planet formation around small stars.

Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our sun. Like many small stars ...

A giant conundrum has been found orbiting a teeny tiny red dwarf star just a fifth of the size of the Sun. Such small stars ...

A possible new dwarf planet has been discovered at the edge of our solar system, so far-flung that it takes around 25,000 ...

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

WASHINGTON (Reuters) -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 dwarf planet, spotting it as it ...

A potential new dwarf planet has been discovered in the outer reaches of the solar system, and its existence poses the ...
