A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close binary system—an arrangement previously thought impossible. Using advanced ...

Is it a two-for-sun deal. Astronomers were blown away after discovering a bizarre exoplanet that orbits twin stars closer than any ever seen before in a binary star system, per a starry study ...

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 cosmos.

Scientists have found evidence of a previously-undetected dwarf planet at the edge of the solar system. The object, dubbed 2017 OF201, follows an extreme, oblong orbit, taking some 25,000 Earth years ...

Planet hunters have grown used to strange worlds, but a handful of discoveries now point to something even more radical: giant planets that loop around their stars on orbits so skewed they almost defy ...

The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...
