Saturn is the second largest planet in the Solar System in terms of size. It has a bright ring composed of icy and rocky particles. Since it is very far away from the Sun, it has an orbital period of about 29.5 years. An astronomical phenomenon called the Opposition of Saturn will occur once about every 378 days.

When the Opposition of Saturn occurs, the Sun, the Earth and Saturn will almost come in a straight line. Saturn will reach its closest distance to the Earth and its highest brightness. A telescope with a 30x magnification is able to see its ring. To see it more clearly, an astronomical telescope with a 200x magnification will be required.

This year, the Opposition of Saturn occurs on Aug 15 (Monday). Saturn can be found rising from the Southeast at night. It can be seen clearly at about 8pm. It has a star magnitude of about 0.3, which will be one of the brightest stars in the night sky.
