Based on the Hubble Sequence, what classification would an irregular galaxy receive?

An irregular galaxy is classified under the Hubble Sequence as "Irr," which stands for "irregular." This classification is specifically designated for galaxies that do not fit into the categories of elliptical or spiral formations due to their lack of distinct structure and symmetry. Irregular galaxies are often characterized by chaotic appearances, with no defined shape or orderly spiral arms like those seen in spiral galaxies. They might exhibit various features and compositions, making them unique and diverse.

In the context of the Hubble Sequence, elliptical galaxies are categorized by their smooth, featureless profiles, while spiral galaxies are recognized for their well-defined arms and central bulges. Barred spiral galaxies are a subtype of spirals that possess a central bar structure. Irregular galaxies stand apart from these classifications, emphasizing their distinct nature in the galaxy taxonomy established by Edwin Hubble.
