Galactic plane

The galactic plane is the plane where the disk of the Milky Way Galaxy lies.

Any object located perpendicularily above this plane is descibed as being X° (degrees) North, and likewise, any object located perpendicularily below this plane is described as being X° South.

The star Beta Lyrae is located 142°NE of the galactic plane. 

The antimatter universe counterpart to the star Minara was a dead star located 12°S of galactic plane. 

While approaching the Questar M-17 in 2269, the Enterprise experienced severe hypergravitional effects from the dead star's negative star mass, pulling it "two minutes right ascension" off course. As they entered orbit of the star Uhura detected a mysterious radio signal coming from an insectoid pod ship located at "nine seconds right ascension from galactic plane, dead ahead" of the Enterprise position in orbit of the star.
