NGC 300 (Caldwell 70)
NGC 300 (also known as Caldwell 70) is a spiral galaxy in the constellation Sculptor. It has an apparent visual magnitude of 9 and its angular diameter is 22 × 16 arc-minutes. NGC 300 lies at an estimated distance of 6.1 million light-years. It is the brightest of the five main spirals in the direction of the Sculptor Group. NGC 300 is inclined at an angle of 42° to our line of sight and shares many characteristics of the Triangulum Galaxy. It is 94,000 light-years in diameter, somewhat smaller than the Milky Way.
