"Contains" nearest quasar?
This article says it is a Seyfert galaxy, and the Seyfert galaxy article (linked from the description here) says that they are not quasars because they have a detectable galaxy. So it seems a quasar can not be contained in a detectable galaxy, and thus this object does not "contain" a quasar. So where is the nearest real quasar? 2A00:23C8:8F9F:4801:61D8:4387:5204:D10D (talk) 11:12, 5 July 2023 (UTC)
