The Cartwheel Galaxy (also known as ESO 350-40 or PGC 2248) is a lenticular ring galaxy about 500 million light-years away in the constellation Sculptor. [1] It has a D 25 isophotal diameter of 44.23 kiloparsecs (144,300 light-years), and a mass of about 2.9–4.8 × 10 9 solar masses; its outer ring has a circular velocity of 217 km/s.
The Cartwheel Galaxy, galaxy pair AM 2026-424, and Arp 147 are all examples of ring galaxies thought to be formed by this process. [ 7 ] In pass-through galactic collisions, or bullseye collisions, an often smaller donor galaxy will pass directly through the disc of an often larger spiral, causing an outward push of the arms from the gravity of ...
The cartwheel galaxy, galaxy pair AM 2026-424, and Arp 147 are all examples of ring galaxies believed to be formed from this process. In pass-through galactic collisions, an often smaller galaxy will pass through the disc of an often larger spiral, causing an outward push of the arms, as if dropping a rock into a pond of still water.

Hoag's Object is an unusual ring galaxy in the constellation of Serpens Caput. [5] It is named after Arthur Hoag, who discovered it in 1950 and identified it as either a planetary nebula or a peculiar galaxy. [6] The galaxy has a D 25 isophotal diameter of 45.41 kiloparsecs (148,000 light-years). [1]
