It is the largest known spiral galaxy with the isophotal diameter of over 717,000 light-years (220 kiloparsecs). [ 1 ] This is a list of largest galaxies known, sorted by order of increasing major axis diameters.
The central spiral is a SB0a type barred-spiral. [6] Malin 1 is peculiar in several ways: its diameter alone would make it the largest barred spiral galaxy ever to have been observed. [4] Malin 1 was found later to be interacting with two other galaxies, Malin 1B and SDSS J123708.91+142253.2.
A spiral galaxy is a type of galaxy characterized by a central bulge of old Population II stars ... 10.1 M101, Pinwheel Galaxy: SAB(rs)cd Ursa Major: 8.3 M104 ...
Size (left) and distance (right) of a few well-known galaxies put to scale. There are an estimated 100 billion galaxies in all of the observable universe. [1] On the order of 100,000 galaxies make up the Local Supercluster, and about 51 galaxies are in the Local Group (see list of nearest galaxies for a complete list).

An example of a spiral galaxy, Messier 77 (also known as NGC 1068) Spiral galaxies form a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae [1] and, as such, form part of the Hubble sequence.
An example of a spiral galaxy (Pinwheel Galaxy). This category contains galaxies in the S (de Vaucouleurs for indeterminate) category or any galaxy where it is indeterminate whether the galaxy is SA, SB or SAB in its spiral nature. SA, S (Hubble) galaxies should be categorized under Category:Unbarred spiral galaxies
