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 ...

Astronomers have discovered six planets orbiting a bright, nearby star in perfect synchrony like a grand cosmic orchestra.

But once upon a time, billions of years ago, a massive object could have passed closely enough to gravitationally stir up the orbits of objects in the outer Solar System, causing the peculiar orbits.

Astronomers recently made an important discovery when they found a rare "in-sync" solar system with six planets all moving in one big grand harmony.

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

Discovered last month by a telescope in Chile, the comet known as 3I-Atlas is only the third known interstellar object to ...

The solar system orbits around the center of the Milky Way — our galaxy — but even within the frame of the solar system, the sun is not exactly static because of the gravitational interaction ...

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 ...

Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago.
