Recent simulations and research have unveiled a fascinating new insight into the history of the solar system’s terrestrial ...

New simulations suggest that up to four of the solar system's rocky planets, including Earth and a long-lost world, once ...

In the dark, icy outskirts of our solar system—far beyond Neptune's orbit—astronomers have discovered a cosmic oddball that appears to be locked in an ...

Resonance happens when planets or moons have orbital periods that are ratios of whole numbers. The orbital period is the time taken for a planet to make one complete circuit of the star.

Its inclined orbit challenges current models of the outer Solar System. Discovered by an international team, this object ...

The moon system has two orbital resonances that give rhythmic and harmonic structure to the otherwise unsteady lullaby-style melody. The first and third moons Mimas and Tethys are locked in a 2:1 ...

The discovery is the second time Cheops has helped reveal a planetary system with orbital resonance. The first one, known as TOI-178, was announced in 2021.

Systems that line up like this are known as orbital resonances. But, despite the theory, finding resonances in the Milky Way is rare. Only 1 percent of planetary systems still preserve this symmetry.

It would have been about the size of Saturn's third-largest moon, Iapetus. Its gravitational pull kept Saturn and Neptune in resonance - where their orbital periods were synchronised.
