NGC 499, also occasionally referred to asPGC 5060,IC 1686 orGC 289, is alenticular galaxy in the constellationPisces.[2] It is located approximately 197 million light-years from theSolar System[4] and was discovered on 12 September, 1784 byastronomerWilliam Herschel.[5]
The NGC 499 Group is named after the galaxy.[3]
The object was discovered by Herschel along withNGC 495 andNGC 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 sonJohn Herschel[5] and independently found byStéphane Javelle in 1899.[6]
