For centuries, astronomers have sought to understand the formation and evolution of the solar system and the dynamics that ...

"For 98% to 99% of the solar system's lifetime, the planets' orbits have been nice and stable," Raymond said. As a result, you can use the planets' current orbital dynamics to make a pretty ...

There’s a new object in the distant reaches of our solar system, and it might just offer clues to a long-standing cosmic ...

ESS2.B: Plate Tectonics and Large-Scale System Interactions (3-5 ... including their elliptical paths around the sun. Orbits may change due to the gravitational effects from, or collisions with, other ...

This may explain the strange properties of the orbits of our solar system's planets, which are not quite perfectly circular, and all lie on slightly different planes. NASA artist’s conception of ...

Astronomers have revealed new research showing that millions of new solar system objects are likely to be detected by a brand-new facility, which is expected to come online later this year.

any smaller (km-scale) bodies called planetesimals, that come close to the giant planets get their orbits perturbed. Sometimes they get directed into the inner solar system, but other times they ...

but with densities closer to the gas giants in our own solar system. Pitts said most of the planets are smaller than Neptune. Their orbits range from nine to 54 days, putting them closer to their ...

Jupiter, roughly 562 million miles from Earth today, has nearly 100 moons. But Batygin and his collaborator Fred Adams' ...

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 ...

The six found so far are roughly two to three times the size of Earth, but with densities closer to the gas giants in our own solar system. Their orbits range from nine to 54 days, putting them ...
