Google translate: Illustration of two celestial bodies are together? Still very far apart it? 图中的两个天体是在一起的？还是相隔很远呢？
Here is an example

Lostlens has looked up the z values: l z = 0.070 z = 0.069 , they are about the same distance away
Use this this calculator to find distance away http://www.wolframalpha.com/input/?i=redshift+z%3D0.5
Use this calculator to find distance apart http://chandra.harvard.edu/photo/scale_distance.html using example 3
