NGC 18 is a double star system located in the constellation of Pegasus.[1] It was first recorded by Herman Schultz on 15 October 1866. It was looked for but not found by Édouard Stephan on 2 October 1882. It was independently observed by Guillaume Bigourdan in November 1886.[1]
Both stars are 2528±20 light-years away, and based on this distance have a minimum separation of approximately 2,700 astronomical units, an unusually wide separation for a binary system.[citation needed]
