An illustration of the solar system showing the orbits of the planets around the sun.

If you need to remember your tiny place in the space-time continuum, it’s time to listen to SolarBeat, a flash animation that converts the orbital frequencies of our solar system into notes ...

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 ...

The enormous visitor to our solar system may have been about 8 times the mass of Jupiter, and come nearly as close to the sun as the orbit of Mars.

Most planet-forming disks have warps that can lead to planets on inclined orbits, which could explain where the tilt of Earth ...

All solar system planets circle our sun with slightly tilted orbits — and a new study shows even distant planetary systems in quiet neighborhoods have orbital tilts, too.

Astronomers have discovered a rare solar system in the Milky Way with six planets orbiting in perfect rhythm like a cosmic orchestra.

The innermost planet completes three orbits for every two by its closest neighbor. It’s the same for the second- and third-closest planets, and the third- and fourth-closest planets.
