asteroid spectral type
spectral classifications of asteroids based on spectral shape, color, and albedo
Descriptionspectral classifications of asteroids based on spectral shape, color, and albedo. To distinguish from different classifications, use qualifier asteroid taxonomy (P1016).
Representsasteroid spectral type (Q1750705)
Data typeItem
Template parameteren:template:Infobox planet spectral_type
Domain

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)

[edit]

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

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)[reply]
