Scope  (2)

Date qualifiers can accept an explicit DateObject or queries that evaluate to a DateObject:

Date qualifiers can also be specified using Dated:

Location qualifiers can accept an explicit GeoPosition, location-based Entity objects, or queries that evaluate to one of these:

Possible Issues  (1)

Pluto is not included in the list of solar system planets:

It is now considered a "dwarf planet":
