Untuk banyak asteroid, nilai ''ρ'' ~2 g/cm<sup>3</sup> telah diasumsikan.
Namun, kepadatan bergantung pada jenis spektral asteroid. Krasinsky ''dkk.'' memberikan perhitungan kerapatan rata-rata asteroid kelas C, S, dan M sebagai 1,38, 2,71, dan 5,32 g/cm<sup>3</sup> . <ref>{{Cite journal|last=Krasinsky|first=G. A.|author-link=Georgij A. Krasinsky|last2=Pitjeva, E. V.|author-link2=Elena V. Pitjeva|last3=Vasilyev, M. V.|last4=Yagudina, E.

Dengan asumsi nilai-nilai ini (daripada saat ini ~2 g/cm<sup>3</sup>) adalah perkiraan yang lebih baik.
== Gravitasi permukaan ==
== Periode rotasi ==
[[Periode rotasi]] biasanya diambil dari parameter [[kurva cahaya]] pada PDS. <ref>{{Cite web|title=Asteroid Lightcurve Parameters|url=http://www.psi.edu/pds/resource/lc.html|publisher=PDS Asteroid/Dust Archive|archive-url=https://web.archive.org/web/20060902224521/http://www.psi.edu/pds/resource/lc.html <!-- Bot retrieved archive -->|archive-date=2006-09-02|access-date=2006-10-21}}</ref>
== Kelas spektral ==
[[Jenis spektral asteroid|Kelas spektral]] biasanya diambil dari [[klasifikasi Tholen]] di PDS. <ref>Asteroid Taxonomies ''PDS Asteroid/Dust Archive''. 2006-10-21.</ref>
== Magnitudo absolut ==
Magnitudo absolut biasanya diberikan oleh survei planet minor [[IRAS]] <ref name="simps" /> atau survei planet minor MSX <ref name="mimps" /> (tersedia di PDS).
