2 Pallas
2 Pallas (au Palasi; alama: .svg){kind=small}
) ni asteroidi ya pili iliyowahi kutambuliwa katika Mfumo wa Jua. Iligunduliwa na mtibabu na mwanaastronomia Mjerumani Heinrich Wilhelm Matthäus Olbers mnamo 28 Machi 1802.[1]
Jina la "2 Pallas" inaunganisha jina lililotolewa na Olbers, pamoja na namba ya asteroidi iliyojulikana. Jina lenyewe limanrejelea Pallas Athena aliyeabudiwa kama mungu katika dini ya Ugirki ya Kale.[2]
2 Pallas ina masi inayokadiriwa kuwa asilimia 7% ya masi yaote ya ukanda wa asteroidi. [3] Ni asteroidi kubwa ya tatu kulingana na masi yake, na ya pili kwa kuangalia kipenyo chake. Umbo lake linafanana na duaradufu yenye vipenyo kati ya km 500 na km 582.
