Editing Supergalactic coordinate system (section)

[[File:SGP(50mln-ly.png|thumb|Galaxies and galaxy clusters {{nobr|< 50 [[mega-|M]][[light-year|ly]]}} away from Earth plotted in the supergalactic plane]]

The '''supergalactic coordinate system''' is a [[reference frame]] for the [[supercluster]] of [[galaxy|galaxies]] that contains the [[Milky Way]] galaxy, referenced to a local relatively flat collection of [[Galaxy cluster|galaxy clusters]] used to define the '''supergalactic plane.'''

The supergalactic plane is more or less [[perpendicular]] to [[galactic plane|the plane]] of the Milky Way; the angle is 84.5°. As viewed from Earth, the plane traces a [[great circle]] across the sky through the following [[constellation]]s:
