Items of an asteroid family should have:
| Property | Data type | description | required |
|---|---|---|---|
| instance of (P31) | Item | that class of which this subject is a particular example and member; different from P279 (subclass of); for example: K2 is an instance of mountain; volcano is a subclass of mountain (and an instance of volcanic landform) . Possible values: asteroid family (Q249083) | yes |
| named after (P138) | Item | entity or event that inspired the subject's name, or namesake (in at least one language). Qualifier "applies to name" (P5168) can be used to indicate which one | yes |

| part of (P361) | Item | object of which the subject is a part (if this subject is already part of object A which is a part of object B, then please only make the subject part of object A), inverse property of "has part" (P527, see also "has parts of the class" (P2670)) | no |
