The NGC 499 Group is named after the galaxy.[3]
The object was discovered by Herschel along with NGC 495 and NGC 496. He initially described the discovery as "Three [NGC 499 along with NGC 495 and 496], 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 [right triangle]; the [right angle] to the south NGC 499, the short leg preceding [NGC 496], the long towards the north [NGC 495]. Those in the legs [NGC 496 and 495] the faintest imaginable; that at the rectangle [NGC 499] 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]
