Have you ever thought about what will happen to our Solar system in a future very far away? It's a question that intrigues not only scientists but anyone who raises their eyes to the starry sky. Recently, a study published on Nature Communications shed light on a fascinating phenomenon: the “swelling” of the Solar System.
The Sun, which has always kept the planets of our system in orbit, is losing mass and, consequently, its “grip” on the planets is loosening. This means that the orbits of the planets are slowly moving apart. For example, every year, Mercury moves away from the Sun by about 0.5-1 cm, while the Earth moves away by 1.5 cm. This may not seem like much, but on cosmic scales, it is a significant phenomenon.
Solar System: This process, however, is not of immediate concern
There is no risk of the planets completely “escaping” the Sun. It is more of an indication of how the Solar System has evolved over time and continues to do so.
Another curiosity concerns the most distant planets, such as Jupiterwhich tend to move further away than those closer to the Sun. This data not only helps us better understand the dynamics of our system but also offers new perspectives on theories of relativity.
And you, what do you think of this slow but inexorable change in our Solar System? Are you curious to know more about how things will evolve in the next billion years?
