Asteroid 2003 MH4, a large space rock, will make a close approach to Earth on May 24, 2025. While not an immediate threat, ...

This week, an old astronomical controversy is renewed as researchers present new evidence for a hidden "Planet X" in our solar system.

Recent discoveries have challenged previous assumptions about the space near Earth, revealing a potential population of undiscovered "minimoons," some ...

Over millions of years, these objects grew larger, sweeping up material in their orbits and becoming the planets we know today. This model of solar system formation is known as the nebular hypothesis.

As our Solar System orbits the Milky Way, it encounters various environments, including dense regions of the interstellar medium. These encounters can expose parts of the Solar System to the ...

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 ...

A planet-size object that possibly once visited the solar system may have permanently changed our cosmic neighborhood by warping the orbits of the ... life Using computer models of the four ...

Perturbations from the giant planets cannot do the job either, even if they change their orbits abruptly later in the Solar System's evolution, as modern models predict (see ref. 5, for example).

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 orbits of the planets around the Sun have been the source for many a scientific debate. Their current orbital properties are well understood but the planetary orbits have evolved and changed since ...
