Riga 43:

La composizione di Pallas è unica, ma abbastanza simile a quella degli [[asteroidi di tipo B]].

Ci sono indicazioni che la composizione superficiale del pianetino sia molto simile alle [[meteorite|meteoiritimeteoriti]] di [[Renazzo]], unadelle [[condrite carbonacea|condriti carbonacee]] (CR).
