Astronomers have discovered a rare planetary system that dances to a cosmic rhythm. Located 105 light-years away in the ...

Beyond Neptune, a celestial object puzzles astronomers with its synchronized motion with the giant planet. Its inclined orbit challenges current models of the outer Solar System. Discovered by an ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers have detected a new exoplanet ...

Astronomers used a telescope in Hawaii to find a new object on the outer edges of our solar system, helping to fuel evidence of a long-standing theory about Planet Nine, or Planet X. For years, ...

You probably already know that gravity can greatly influence cosmic objects as they make their way through space. We see this constantly in how the Sun's gravity causes planets to orbit it. And even ...

Washington, DC – Three new objects locked into roughly the same orbit as Neptune–called “Trojan” asteroids–have been found by researchers from the Carnegie Institution’s Department of Terrestrial ...

Despite the apparent intersection of their orbits in two dimensions, Neptune and Pluto's 3:2 orbital resonance prevents them from ever occupying the same three-dimensional space simultaneously.

A passing star, or a stellar flyby, with the potential to pull Neptune out of its orbit by just 0.1%, could mean catastrophe for the entire solar system. But don’t worry — it won’t happen in our ...

Researchers have shared a radical new idea for how to put a spacecraft in orbit around Neptune: Use the thin atmosphere of Triton, Neptune's largest moon, to capture it. When you purchase through ...
