The "pinwheel" shape is usually called "spiral".
It is known as an irregular galaxy. A few different Classifications are : Irr L (some structure) Irr LL (No visible structure) Also Dward Irregulars : DL DLRRS (Low Metallicity)
A regular 2-dimensional shape with 6 sides is called a hexagon.A regular 3-dimensional shape with 6 sides is called a cube.
pentagon
Not surprisingly, it would be called an irregular galaxy.
The same stellar materials and dust any other galaxy is made of - it just hasn't taken on a coherent shape - yet, or possibly it had a collision encounter with another galaxy, leaving it "irregular" - either is possible.
hexagon
A square.
The shape is called a decagon. If all the sides and angles are the same, it is called a regular decagon.
