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 ...

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

Giant planets are not rare per se — after all, we have four in our own solar system. Such large worlds are, however, rarely ...

As a result of the International Astronomical Union’s 2006 demotion of Pluto from planet to dwarf planet, our solar system ...

Astronomers discover giant gas planet TOI-6894b orbiting a tiny red dwarf, rewriting what we know about planet formation.

Scientists have discovered a giant planet called TOI-6894b, orbiting a star that should be far too small to have formed it.

It had not been thought possible that such tiny, weak stars could provide the conditions needed to form and host huge planets.

For the unversed, "Planet Nine" is a hypothetical planet which is reportedly larger than Earth that is thought to orbit ...

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.
