Open nn:Spesial:AboutTopic/Q1087678 and note that the link in the sidebar box for "In other languages" for English Wikipedia goes to en:Category:Tempe_Terra. This should go to en:Tempe_Terra according to the item on Wikidata, that is d:Q1087678.
A strange thing is that the item has a link to a commons category which is missing at the special page.
