Saturn has three main rings, give or take.

土星有三个主环。

The E ring can be found outside the planet's brighter main rings.

E环可以在行星较亮的主环之外找到。

There are three main rings: two narrow and one broad.

两个窄的，一个宽的。

There are quite a few gaps in the rings caused by moons; in fact, there are hundreds of “ringlets” in the main rings.

有不少土星环中的空隙是由卫星造成的；事实上，在主环中还有数百个“小环”。

And if the drops are the right size, the first red supernumerary ring can overlap significantly with the main dark blue ring, and what do red and blue give?

会叠加在主环的深蓝环上红加蓝等于 紫色？
