NGC 7015 is a spiral galaxy located about 203 million light-years away from Earth in the constellation Equuleus.^[3] NGC 7015's calculated velocity is .^[4] NGC 7015 was discovered by French astronomer Édouard Stephan on September 29, 1878.^[5]

NGC 7015 has two symmetric inner arms, with muliple long and continuous outer arms.^[6] It is also host to a supermassive black hole with an estimated mass of 8.2 × 10⁷ M_☉.^[7] NGC 7015 is a member of a group of galaxies known as the NGC 7042 Group. This group contains ten galaxies, with the group named after its brightest member, NGC 7042. Besides NGC 7015, the group also contains, NGC 7025, NGC 7042, NGC 7043, and IC 1359.^[8]
