The number two gas giant planet is the Saturn, undoubtedly one of the most spectacular planets in the Solar System. The surface of the planet itself has a much poorer texture than Jupiter's, but this is distracted by the ring system around the planet. You have to admit, we do it right.

Among the planets we know, this planet has a ring system that is easy to observe for amateurs. The ring is an abundance of dust and ice, complemented by small or larger pieces of stone up to a few meters in length. The ring system is subdivided according to the size of the particles. Its thickness is negligible (varying from about 10 m to 1 km), so that when the ring is flush with the earth, the ring almost disappears. The previous ring turning event took place in 2009. The next one will be in 2025, but then we will only cross the plane of the rings once. Turnovers occur every 29.5 years, between 15.75 and 13.75 years.

The image shows the largest gap between rings, known to astronomers as the Cassini gap. The gap, named for the French astronomer, is between the A and B rings. Ring A has an outer darker color and Ring B has a larger, lighter shade. The other rings (maybe the C-ring is still dim) and the smaller Encke, due to limited capabilities, unfortunately I could not record.

Saturn's observability in these years is not exactly from the best of our country, as it is located in the lowest part of the ecliptic, and as a result, the atmosphere greatly deteriorates its observability and recordability.
