NGC 55 Group - The Missing 12
Posted: 19.11.2020, 23:57
A generally neglected galaxy group with 18 member galaxies (half of which clash with the Local Group), this seems like a great, chill place (for worldbuilders) - not too far, not too close. Surely this place should be concretely known, right? Hahaha, not at all!
After 5 days of researching on 4 different places (SIMBAD, NED, VizieR, and HyperLEDA), some Excel shenanigans and GeoGebra 3D plotting, a Perl script, and even Mamajek's stellar relations table (don't ask), I present to you:
The NGC 55 Group
Where membership is hard to determine
Here is a rough 3D plot of the cluster in GeoGebra 5 (open to view the animation):
Special thanks to LukeCEL and Fridger, for making the Perl script that converted HyperLEDA data to AxisAngle values whenever possible

- Minor galaxies

- Galaxies are represented by points, while the possible subgroups are represented by red spheres.
