• They are usually a red or yellow color, with mainly old stars.
• Unlike the spiral galaxy, there isn't much gas or dust.

Irregular Galaxies

• An irregular galaxy is a galaxy that does not fit under either the spiral or elliptical galaxy types.
• It can be called deformed either from the pull of other galaxies or by running into other galaxies.

Dwarf Galaxies

• Dwarf Galaxies are very small galaxies.
• They are usually near or by large galaxies.
• Sometimes, they will merge into other galaxies.
