UGC 7069 is a very large ring galaxy located about 760 million light years from Earth in the constellation of Ursa Major. It is currently the largest ring galaxy discovered with a diameter of approximately 115 kiloparsecs (~390,000 light-years) making it twice the diameter of the Cartwheel Galaxy which for reference has a diameter of roughly 45.9 kiloparsecs. It is a starburst galaxy with high star formation rate (SFR) of 13 solar masses per year.
