The galactic plane is inclined at an angle of 45° ± 5° to the plane of the sky, with the major axis oriented along a position angle of 195° ± 3°. [9] This is classified as a LINER-type galaxy and may be in a post-starburst phase. There is an extended or double source of X-ray emission. [10] Two supernovae have been observed in NGC 5371.
The galactic plane is the plane on which the majority of a disk-shaped galaxy's mass lies. The directions perpendicular to the galactic plane point to the galactic poles. In actual usage, the terms galactic plane and galactic poles usually refer specifically to the plane and poles of the Milky Way, in which Planet Earth is located.
The galactic coordinate system uses the approximate plane of the Milky Way Galaxy as its fundamental plane. The Solar System is still the center of the coordinate system, and the zero point is defined as the direction towards the Galactic Center. Galactic latitude resembles the elevation above the galactic plane and galactic longitude ...
The galactic coordinate system is a celestial coordinate system in spherical coordinates, with the Sun as its center, the primary direction aligned with the approximate center of the Milky Way Galaxy, and the fundamental plane parallel to an approximation of the galactic plane but offset to its north.

Supergalactic and Ecliptic plane. The zero point (SGL = 0°, SGB = 0°) [3] lies in the constellation Cassiopeia, coincides with (l x = 137.37°, b x = 0°) and was chosen for convenience to lie along the line where the supergalactic plane intersects with the galactic plane. In J2000 equatorial coordinates, this is approximately RA = 2.82 h ...
The Zone of Avoidance (ZOA, ZoA), or Zone of Galactic Obscuration (ZGO), [1] [2] is the area of the sky that is obscured by the Milky Way. [ 3 ] The Zone of Avoidance was originally called the Zone of Few Nebulae in an 1878 paper by English astronomer Richard Proctor that referred to the distribution of " nebulae " in John Herschel 's General ...
The result yields a direction perpendicular to the galactic plane. [1] In the case of the Milky Way, this is given by the coordinates of the galactic pole. Galactic clusters [2] [3] are gravitationally bound large-scale structures of multiple galaxies. The evolution of these aggregates is determined by time and manner of formation and the ...
