The Virgo cluster lies within the Local Supercluster, and its gravitational effects slow down the nearby galaxies. 室女座星系团位于本超星系团之中,他的重力影响减缓了邻近星系的速度。
This effect is seen as a deviation from the uniform Hubble expansion of the galaxies and provides a measure of the mean density within the Virgo Supercluster. 这作用被视为背离银河哈勃膨胀的统一而提供对室女座超星系团内平均密度的测量。
