What lenticular and ring galaxy is located in the Sculptor constellation 500 million light-years away from Earth?

The Cartwheel Galaxy is located in the constellation Sculptor. It was discovered in 1941 by Fritz Zwicky, who said at the time that it was one of the most perplexing structures awaiting an explanation in terms of star dynamics. The galaxy's estimated diameter was determined to be 150,000 light-years, which is somewhat smaller than the Milky Way.
