This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...

Astronomers have captured a rare and remarkably close view of a giant planet circling a pair of tightly bound suns, offering one of the clearest real-world echoes yet of the fictional world Tatooine.

Nearby red dwarfs are turning into rich laboratories for studying small rocky worlds. One such star now stands out as a system with four or more planets, including at least one in the habitable zone ...

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 ...

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.

The discovery of a planetary system “out of whack,” where the orbits of two planets are at a steep angle to each other, was reported today (May 24) by a team of astronomers led by Barbara McArthur of ...

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 ...

In theory, it could happen – one of the very first solutions to the three-body problem was this scenario. But it is very unlikely to be stable over time. You need the stars to have near equal mass and ...
