This type of gravitational alignment is called orbital resonance, and it's like a harmony between distant planets. I'm an astronomer who studies and writes about cosmology. Researchers have ...

Each of those periods is about 1.5 times the next, meaning the planets are in a configuration called a 3:2 (pronounced "three to two") mean motion resonance. For every three orbits of the ...

placing the planets further away from the MMR. In this work, we will discuss how the tidal interactions with the central star play an important role in shaping the period ratios and resonant angles in ...

Furthermore, the planets' orbits are linked in a mathematical relationship called a resonance chain, with a pattern that is unique among the known planetary systems in our galaxy. Studying the ...
