What is the planet found in saturns rings called

I read in an astronomy book (atlas of the southern night sky second edition) that there was a planet found in the rings of saturn....

I think you are talking about Pan and Daphne. These are moons, not planets, and they ARE IN Satrun's rings.

'...Ring shepherdsMain article: Rings of Saturn
Shepherd satellites are small moons that orbit within, or just beyond, a planet's ring system. They have the effect of sculpting the rings: giving them sharp edges, and creating gaps between them. Saturn's shepherd moons are Pan (Encke gap), Daphnis (Keeler gap), Atlas (A Ring), Prometheus (F Ring) and Pandora (F Ring).[14][18] These moons together with co-orbitals (see below) probably formed as a result of accretion of the friable ring material on preexisting denser cores. The cores with sizes from one-third to one-half the present day moons may be themselves collisional shards formed when a parental satellite of the rings disintegrated.[30]...."

I'm pretty sure you are talking about Enceladus. It is responsibl;e for the E ring in which it's orbit resides, and is a possible location to find life. There is LOTS of water there. And it's a moon of saturn.Unless they found Nibiru and I haven't heard? haha

I think you misread that. There is no planet in Saturn's rings. Saturn does have quite a few moons, but none of them are in the rings.

The planet Saturn! 6th planet from the sun.
