This term indicates an apparent vacuum in the outer part of Saturn's A ring.
As is known, this planet is characterized by a series of rings - made up of ice particles -, the most obvious of which, from the outside, are called with the letters A, B, C and D. While A and B they are separated with a well-marked division, called Cassini, by the name of its discoverer, the A is furrowed by a thin division called Encke, from the name of the German astronomer who discovered it in 1837; The division, due to its extreme finesse, is also called a pencil stroke.
Recent close observations of the Saturnian world have shown that this division, as well as that of Cassini, is characterized by a relative absence of particles with respect to other regions of the rings, and not by an absolute vacuum of matter as the first e imprecise observations from Earth.
