asteroid spectral type
spectral classifications of asteroids based on spectral shape, color, and albedo

Description	spectral classifications of asteroids based on spectral shape, color, and albedo. To distinguish from different classifications, use qualifier asteroid taxonomy (P1016).
Represents	asteroid spectral type (Q1750705)
Data type	Item
Template parameter	en:template:Infobox planet spectral_type
Domain	According to this template: astronomical object (Q6999): asteroid (Q3863) According to statements in the property: asteroid (Q3863) When possible, data should only be stored as statements
Allowed values	asteroid spectral types - asteroid spectral type (Q1750705) (note: this should be moved to the property statements)
Example	According to this template: 110 Lydia (Q135916) => X-type asteroid (Q2314759) qualifier asteroid taxonomy (P1016) => SMASS classification (Q12899355) => M-type asteroid (Q847310) qualifier asteroid taxonomy (P1016) => Tholen classification (Q15141841) 4 Vesta (Q3030) => V-type asteroid (Q1400344) According to statements in the property: 4 Vesta (Q3030) → V-type asteroid (Q1400344) 6 Hebe (Q107509) → S-type asteroid (Q543157) When possible, data should only be stored as statements

Type “asteroid (Q3863)”: item must contain property “instance of (P31)” with classes “asteroid (Q3863)” or their subclasses (defined using subclass of (P279)). (Help)

List of violations of this constraint: Database reports/Constraint violations/P720#Type Q3863, hourly updated report, SPARQL

Value type “asteroid spectral type (Q1750705)”: This property should use items as value that contain property “instance of (P31)”. On these, the value for instance of (P31) should be an item that uses subclass of (P279) with value asteroid spectral type (Q1750705) (or a subclass thereof). (Help)

Qualifiers

To distinguish from different classifications, you can use the property asteroid taxonomy (P1016). --Paperoastro (talk) 22:36, 9 November 2013 (UTC)

How do I insert something like Cg, which is SMASS classification? This property (P720) allows only something like C-type or D-type, but that is Tholen-classification. Should I create new items for this? --Goldzahn (talk) 04:32, 18 September 2019 (UTC)
