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

Observation history

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]

gollark: They are wrong, then.
gollark: Really, indentation doesn't matter much. IDEs can pretty trivially convert between different types. Though admittedly tabs are easier to convert than spaces.
gollark: I respect people who don't use vertical tab indentation, but their opinion is wrong.
gollark: Bots spam much more effectively than humans.
gollark: * those
