NGC 512, also occasionally referred to as PGC 5132 or UGC 944, is a spiral galaxy in the constellation Andromeda.

[2] It is located approximately 217 million light-years from the Solar System[4] and was discovered on 17 November 1827 by astronomer John Herschel.

The position is just 23" from UGC 944, thus the two objects are generally regarded as equivalent.

[5] The galaxy has an apparent size of 1.6 × 0.4 arcmins and appears very elongated.

The distance of NGC 512 from the Solar System can be estimated using Hubble's law, which puts the object at roughly 220 million light-years from the Sun.
