As planetary systems evolve, gravitational interactions between planets can fling some of them into eccentric elliptical orbits around the host star, or even out of the system altogether. Smaller ...

Beyond the orbit of Neptune, in the cold and nearly empty reaches at the frontier of the solar system, astronomers suspect a large planet may be hiding in the dark. No telescope has ever photographed ...

Gravity not only maintains the stability of these orbits but also influences phenomena like tides on Earth, caused by the moon's gravitational pull. The paper, authored by David Jewitt from the ...

In the cold, dark outskirts of planetary systems far beyond the reach of the known planets, mysterious gas giants and planetary masses silently orbit their stars—sometimes thousands of astronomical ...

Astro Brief is a podcast collaboration between KSMU, the Missouri Space Grant, and MSU's Department of Physics, Astronomy and Materials Science. Hosted by Dr. Mike Reed, Astro Brief focuses on ...

A massive interstellar object passing through our solar system during its formative years likely altered the orbits of planets into trajectories observed today, a new study says. Interactions with ...

Zayed Khan Breaks Down While Immersing Mom Zarine Khan’s Ashes; Sanjay Khan Bids Tearful Goodbye Sikh woman goes to Pak as pilgrim, goes missing: First a nikahnama, then crime record, now a video ...

EVANSTON, Ill. — Except for the fact that we call it home, for centuries astronomers didn’t have any particular reason to believe that our solar system was anything special in the universe. But, ...

An international team of astronomers has discovered eight new extrasolar planets, bringing to nearly 80 the number of planets found orbiting nearby stars. The latest discoveries, supported by the ...

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 ...
