Check this out, While manually searching for interacting galaxies, I found this:
Four Galaxies in a three dimensional pyramid shape, one at each of the 4 corners. Whoa!
Take a look at it and spin around seeing just how close all the distances are.
NGC 4007 (also said to be NGC 4005) in the constellation of Leo is highlighted.
Comparing this SE image to a real astronomical image, you can see the same 4 galaxies.
They are part of the [SPD2011] 56765 Cluster of Galaxies (including NGC 4015 & NGC 4022).
& [CHM2007] LDC 854 Group of Galaxies (includes NGC 4018, NGC 3983, NGC 4005, NGC 4015, NGC 3997, NGC 4022, NGC 3993, & NGC 3987).
& [CHM2007] HDC 685 Group of Galaxies (includes NGC 4018, NGC 4005, NGC 4015, NGC 3997, NGC 3987, NGC 4022, & NGC 3993).
Siblings to NGC 4007 (a.k.a. NGC 4005) include NGC 3983, NGC 3987, NGC 3993, NGC 3997, NGC 4015, NGC 4018, & NGC 4022.
I found this amazing online astronomical data center when trying to find an image of the galaxy.
It has EVERYTHING! The Aladin interactive sky atlas is downloadable to your desktop too, WOWSERS!
