There are many Galaxy types in The Appearance Universe (Realms), these are all chosen by their visual and phyical state.
Core types[]
There are 4 different core types, including broad, and normal.
Normal[]
A normal core is just one with a cluster of planets in an almost perfect circle.
Broad[]
A broad core is more of an oval than a circle, the placement of bodies seems to be streched almost.
Spore shaped[]
A Spore Shaped can be any shape with random clusters of planets coming from the core, making the shape seem circle, but with random blobs coming off it.
Irregular[]
Irregular cores are just any cores other than the ones stated, these have not yet been classified.
Outer types[]
Outer types are the other parts from the core types, if that makes sence...
Circle[]
A circle is just a cluster of planets that surrounds the core and planets never connect to it.
Galaxy Outer types.
Arc/Segment[]
An Arc/Segment is just a part of the Circle been cut off, semi-circles come into this class. It's basically a shape that doesn't form a circle around the core without touching it.
Weak Spiral[]
A Weak spiral has arms that come off from the core. They do no bend as much as a Heavy Spiral.
Heavy Spiral[]
A Heavy spiral is just one that bends alot more than a weak spiral.
Breaking Segment[]
This is just a segment with an irregular break in it.
LSH Arm[]
An LSH Arm is a Line-Spiral arm, it is a straight line coming from the core then viciously turning into a spiral.
Line[]
A Line is just a line of bodies coming out of the core and heading straight out. These are very uncommon.
Dot[]
Dots are just a group of bodies that form a shape near to being a circle and not touching the core.
