NGC 7001 is an intermediate spiral galaxy[3] located about 300 million light-years away in the constellation Aquarius.[4] NGC 7001 has an estimated diameter of 123,000 light-years. It was discovered by English astronomer John Herschel on July 21, 1827, and was also observed by Austrian astronomer Rudolf Spitaler on September 26, 1891.[5]

NGC 7001 has tightly wound spiral arms similar to the galaxy NGC 488.[6] The galaxy is also host to a supermassive black hole with an estimated mass of 7 × 107 M☉.[7]
