Distance to sun |
The distance of the group members is stated by NGC4169 180 Mio. Ly. NGC 4174 and NGC4175 192 Mio Ly and 190 Mio Ly. The fourth memeber of the group NGC4173 only 63 Mio Ly. For the galaxy cluster Abell 1495 I found at NED around 656 Mpc . Corresponding light travel time 1,747 Gy. Abell 1495 has a redshift of z=0.141974 found at NED. |

Description |
The Box. Their distances are a clear sign for the interaction between these three galaxies. The forth one, NGC4173 is surely not interacting with the other three galaxies because theri distance is only 63 mio Ly. Abell 1495 The galaxie Cluster Abell 1495 appears in a yellow color because of it's redshift. |
