NGC 4459

NGC 4459 is a lenticular galaxy located about 50 million light-years away[2] in the constellation of Coma Berenices.[3] NGC 4459 is also classified as a LINER galaxy.[2] NGC 4459 was discovered by astronomer William Herschel on January 14, 1787.[4] NGC 4459 is a member of the Virgo Cluster.[5]

Physical characteristics

Dust disk

NGC 4459 has a central flocculent dust disk that surrounds an inner ring.[6][7] Also, there appears to be evidence of ongoing star formation in the disk .[7]

Super massive black hole

NGC 4459 has a supermassive black hole with an estimated mass of roughly 70 million suns (7×107 M☉). Its diameter is estimated to be around 2.87 astronomical units[8] (266.4 million mi).[9]

gollark: A file input's value attribute contains a DOMString that represents the path to the selected file(s). If the user selected multiple files, the value represents the first file in the list of files they selected. The other files can be identified using the input's HTMLInputElement.files property.
gollark: Yep, that's right, some of my code actually obeys some law or other.
gollark: Oh, and in potatOS Lua you can *also* do: `(1 / " ") * string`
gollark: So you can do roughly the same things fairly easily.
gollark: Lua, sadly, doesn't have string split built in, but does have a ton of weird regexy string manipulation functions builtin.
