If Brown’s hidden world is real, Rubin will almost certainly find it or strong indirect evidence that it exists. “In the ...

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 ...

“We predict the existence of an Earth-like planet and several TNOs on peculiar orbits in the outer solar system,” write the authors, Patryk Sofia Lykawka of Kindai University, Japan and ...

The work joins other studies that have proposed interstellar flybys to explain eccentricities in the orbits of certain objects in the solar system. The solar system is approximately 4.6 billion ...

Their current orbital properties are well understood but the planetary orbits have evolved and changed since the formation of the solar system. Planetary migrations have been the most prominent ...

As well as planets and moons, the solar system also contains dwarf planets, which are too small to be considered planets. The best known of these is Pluto, an ice dwarf that orbits far from the ...

Since the formation of the Solar System, the orbits of the planets have evolved and changed over time. While one of the most prominent ideas in the last few decades is planetary migrations and the ...

“By analyzing the reflectivity, and the orbits, we found that our solar system contains two different types of dark comets.” Inner dark comets can be found within the inner solar ...
