**Why are orbital resonances important for science? ** Orbital resonances are the source of both sta
 depending sensitively upon parameters and initial conditions.
[**Orbitally resonant systems**](https://t.me/askmenow/3639) **are extremely important to find because they tell [****astronomers**](https://t.me/askmenow/3435) **about the formation and subsequent evolution of the planetary system.**
Planets around stars tend to form in resonance but can easily have their orbits thrown around, e.g. after a close encounter with a passing star.
As a result, __only one percent of all the multi-planet systems stay in resonance__, according to researchers.
🔭That’s why astronomers observe planetary systems around stars that are believed to harbour planets in resonance.
⬆️ Such [a rare star system](https://www.nature.com/articles/s41586-023-06692-3) with 6️⃣ exoplanets has been recently discovered with an architecture unchanged for billions of years. This star, **HD110067**, lies 100 light-years away in the northern constellation of Coma Berenices, and is the brightest known system with 4️⃣ or more planets.
