Travel through time to witness some of the most remarkable episodes in our solar system's history, uncovering its ancient ...

Moreover, as the planets orbit in the plane of the solar system, they change their direction-of-motion continuously, with Earth returning to its starting point after 365 days.

This will almost always result in a net redshift, as it includes the expansion of the universe, and also our solar system’s motion toward or away from the galaxy we are observing (the rotation ...

Our solar system is technically divided into several different parts. We live in the inner solar system, which includes Mercury, Venus, Earth and Mars (and each of the moons that belong to Earth ...

A study simulated what would happen if a super-Earth orbited in the middle of our solar system, and the results are chaotic.

The planets of our solar system change in position while orbiting a central star, the sun. But does the sun itself move within the solar system?

The Sun, the planets, and all else that constitutes the solar system are hurtling toward the star Lambda Herculis, some 370 light-years away.

Astronomers have observed an object that originated from beyond our solar system, thought to be an interstellar comet, speeding through our celestial neighborhood.
