LEDA 1000714[3] is a ring galaxy in the constellation Crater. LEDA 1000714 is one of a very rare group of galaxies called Hoag-type galaxies,[3] named after the prototype, Hoag's Object – it is estimated that roughly 0.1% of all galaxies are this type.[5][6]
LEDA 1000714 is unusual because it is a Hoag-type galaxy with two nearly round rings, but with different characteristics.[7] It has been nicknamed Burçin's Galaxy, after Burçin Mutlu-Pakdil,[3] the leader of the photometric study of this galaxy.
