NGC 1570, mistakenly called NGC 1571, is a faint galaxy located in the southern constellation Caelum, the chisel. It has a blue magnitude of 13.2,[4] making it visible through a medium sized telescope. Based on a redshift of z = 0.014760,[2] the object is estimated to be 198 million light years (60.9 megaparsecs) away from the Local Group.[3] It appears to be receding with a heliocentric radial velocity of 4,392 km/s.[2]

NGC 1570 has a galaxy morphological classification of S0,[5] indicating that it is a lenticular galaxy. It has also been catalogued as a peculiar elliptical galaxy. The central black hole has a mass 297 times that of the Sun.[9] It is estimated to be 8.9 billion years old, younger than the Milky Way. The average iron abundance of the galaxy is 135% that of the Sun's. NGC 1570 is said to be round in shape, making it more likely to be an elliptical galaxy.[10]

The galaxy was first discovered by Sir John Herschel in November 1835. A month later, he observed NGC 1570 again and mistakenly called it NGC 1571 due to imprecise coordinates. NGC 1570 is part of a small galaxy group called LDC 302.[3] It is the brightest member.
