Polaris, also called the North Star, is just about in line with the north pole and so does not appear to move across the sky as other stars do.

A neutron star is the "end of the line" for a giant star that exploded as a supernova. The material in a neutron star is packed so densely that a chunk of it the size of a cigarette package would weigh thousands of tons. It spins rapidly, at a steady rate (they are sometimes called "radio beacon stars").

The Milky Way is a huge group of stars, somewhere between 200 and 400 billion stars. The stars themselves, or the Milky Way in its entirety, is not in line with anything.
