银河平面

银河平面是银河系主要的质量形成的盘状平面,垂直于银河平面的方向指向银极。通常的使用,在实际的情况下,"星系平面"和"星系极"这两个项目就是特指地球所在银河系的平面和极点。

有些星系是不规则的,无法明确的定义盘面,即使是像银河系一样的螺旋星系,也会因为星星没有完全共平面,也难以明确的定义出星系平面。在1959年,IAU使用1950年分点的历元定义银河系的北银极的精确位置是RA= 12h49m,Dec = 27°24′;目前使用J2000历元,再修正岁差之后,它的位置是RA 12h51m26.282s,Dec 27°07′42.01″。这个位置在后发座,靠近明亮的恒星大角星;同样的,南银极在玉夫座

Galactic plane 银河平面

Galaxy NGC 4452 is being viewed edge-on from Earth, showing its galactic plane with the nucleus at center.This edge-on view of the spiral galaxy NGC 891 shows a profile of a dusty galactic plane.

The galactic plane is the plane in which the majority of a disk-shaped galaxy's mass lies. The directions perpendicular to the galactic plane point to the galactic poles. Most often, in actual usage, the terms "galactic plane" and "galactic poles" are used to refer specifically to the plane and poles of the Milky Way, which is the galaxy in which the Earth is located.
