New discoveries of objects in the Kuiper Belt have also presented challenges for the Planet Nine theory. The latest is known ...

It orbits not two stars but two brown dwarfs - celestial objects too small to be a star and too big to be a planet. And its orbit is unlike any other such planet on record.

Jupiter is our solar system's largest planet. The two brown dwarfs are gravitationally bound and orbit near to each other - as close as just 4% of the distance between Earth and the sun.

A planet circling at a sharp 90-degree angle to the orbits of its two host stars has now been confirmed. This discovery challenges long-standing ideas about how planets form and orbit in the ...

The Very Large Telescope in Chile has found, for the first time, an infant planet nestled in spiral arms of dust around a distant sun-like star.

The two brown dwarfs are gravitationally bound and orbit near to each other - as close as just 4% of the distance between Earth and the sun. The planet, named 2M1510 (AB) b, orbits around this pair.

An artist's impression shows the exoplanet 2M1510 (AB) b's unusual orbit around a pair of brown dwarfs, objects bigger than gas-giant planets but too small to be proper stars. The newly discovered ...

Jupiter is our solar system’s largest planet. The two brown dwarfs are gravitationally bound and orbit near to each other – as close as just 4% of the distance between Earth and the sun.

The nature of this planet's orbit also is unique. Rather than following the plane established for the orbit of the two brown dwarfs, the planet instead orbits almost nearly perpendicular from the ...
