NGC 499, also occasionally referred to as PGC 5060, IC 1686 or GC 289, is a lenticular galaxy in the constellation Pisces.[2] It is located approximately 197 million light-years from the Solar System[4] and was discovered on 12 September, 1784 by astronomer William Herschel.[5]

The NGC 499 Group is named after the galaxy.[3]

Observation history

The object was discovered by Herschel along with NGC 495 and NGC 496. He initially described the discovery as "Three , eS and F, forming a triangle.". As he observed the trio again the next night, he was able to make out more detail: "Three, forming a ; the to the south NGC 499, the short leg preceding , the long towards the north . Those in the legs the faintest imaginable; that at the rectangle a deal larger and brighter, but still very faint."[6]

NGC 499 was later also observed by William Herschel's son John Herschel[5] and independently found by Stéphane Javelle in 1899.[6]
