More general[edit]

@Tobias1984, Sjoerddebruin, Mbch331, Pikolas: This property looks too solarsentric. It's not useful for any moon, articifical satellite, or anything orbiting anything but the sun. Apoapsis looks to me like a more general property. This property is young, it is not to late to change. There are maybe some examples of objects where it is not obvious what it is related to, like objects in the Pluto-Charon system and other objects in binary/trinary systems. For those we can use properties like relative to (P2210) as a qualifier. -- Innocent bystander (talk) 15:22, 18 October 2015 (UTC)

This was proposed by Yair rand and nobody suggested it on the proposal page. I don't see any problems in changing it. Mbch331 (talk) 15:59, 18 October 2015 (UTC)
@Innocent bystander: Good idea. Aphelion can still be an alias. Can you also review the other properties on Wikidata:Property proposal/Space. --Tobias1984 (talk) 16:27, 18 October 2015 (UTC)
Please also review my proposal of "Periapsis_date". I am not fully pleased with the "significant event"-solution. -- Innocent bystander (talk) 20:11, 18 October 2015 (UTC)
