NGC 300 is a galaxy with a pronounced spiral structure (type Sc) in the constellation Sculptor in the southern sky. It has an angular dimension of 19 '× 12.9' and an apparent magnitude of 8.1 mag. It is around 5 million light years away from the Milky Way and, with a diameter of around 45,000 light years, is significantly smaller than our Milky Way with a diameter of around 100,000 light years.
NGC 300 and the irregular galaxy NGC 55 have been considered part of the Sculptor group by many astronomers . The most recent measurements of these galaxies have shown that they are only in the vicinity of this galaxy cluster .
The object was discovered on August 5, 1826 by the Scottish astronomer James Dunlop .
