NGC 1560 is a spiral galaxy in the constellation of the Giraffe in the Maffei Group .
The object was discovered by Wilhelm Tempel on August 1, 1883.
The distance measurement using the cosmological redshift method is not applicable due to the relative proximity of this spiral galaxy. It has a negative radial velocity of −35 k m / second . Until recently, other methods have been used to estimate distances between 5 and 15 million light years . The current, most precise results come to a result of 10 to 12 million light years. At this distance, however, the galaxy is no longer part of the Local Group .
Derived from the distance on the one hand and the apparent size of 11.6 × 1.9 arc minutes on the other, this galaxy has a diameter of around 35,000 light years.
