Scientists believe that such an event could explain the changes in Solar System planetary orbits, including the moderate eccentricities and inclinations observed today. The team also called for ...

Jan. 15, 2025 — New observational data and simulation models have confirmed a new type of planet unlike anything found in the Solar System. This provides another piece of the puzzle to ...

Here’s how it works. A planet-size object that possibly once visited the solar system may have permanently changed our cosmic neighborhood by warping the orbits of the four outer planets ...

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 ...

The terrestrial planets are the four innermost planets in the solar system ... Icy Enceladus orbits within the densest part of Saturn’s E Ring, and has recently been shown to be the source of that ...

All of our solar system’s planets are lining up to parade ... It isn’t a perfect line of planets, because their orbits are tilted slightly, but it is fairly close. The multiverse could be ...

All must, then, be regarded as having always been members of the solar system, however much their orbits may have changed. They are supposed to be derived from the secondary nuclei of a soiral nebula.

While not a detection of life itself, this study shows that the Solar System may have been far more conducive to life in its distant past then we previously believed. Some 4.5 billion years ago ...

All solar system planets have fairly circular orbits with relatively minuscule differences in their distance from the sun at aphelion and perihelion. Venus and Neptune follow the most circular orbits.

The solar system consists of stars, the Sun, 8 planets, dozens of moons, millions of asteroids, comets, and meteoroids. It orbits the centre of the Milky Way galaxy at about 515,000 mph.
