Newer source lists Mass ≈ 2.39×1019Kg Will wait 1 week for feedback on this one before updating. Abyssoft 04:47, 4 September 2006 (UTC)
 * Here's what mass estimates i've been able to track down:
 * {| class="wikitable"

! Author || Year || Mass (in Solar mass × 10-12) || note || link 
 * - align="center" style="align:center; background:#ffc0c0"
 * Pitjeva || 2004 || 5.2 ± 0.8 || ||
 * Kuznetsov || 2001 || 15.6 ± 3.8 || repeated by Kochetova ||
 * Kochetova || 2004 || 14.1 ± 1.4 || reference mentioned in the link above ||
 * Kuznetsov || 2001 || 15.6 ± 3.8 || repeated by Kochetova ||
 * Kochetova || 2004 || 14.1 ± 1.4 || reference mentioned in the link above ||
 * Kochetova || 2004 || 14.1 ± 1.4 || reference mentioned in the link above ||
 * Chernetenko et al || 2005 || 12.0 ± 0.9 || the webpage mentioned above (same group as Kochetova) ||
 * Pitjeva || 2005 || 6.3 ± 0.1 || IAU Ephemeris ||
 * }
 * The new estimates seem to agree with each other here, but they give pretty mad densities for an S-type asteroid. Even the latest slightly smaller value of 12.0 leads to 5.6 g/cm³. I might believe that for an M type, but it looks pretty suspicious here.

I would go with the old Pitjeva value and maybe reference the new website next to it for completeness. Deuar 23:30, 4 September 2006 (UTC)
 * I updated the above table and the article to use the latest Pitjeva values. —RP88 17:51, 15 March 2007 (UTC)

Hi resolution images
An article posted on arxiv has high resolution images, discusses its shape, density and possible craters. Agmartin (talk) 16:57, 26 February 2019 (UTC)

Density
I tried to calculate the mean sensity. It it turned out to be much less than the figure given in the info box. I’ll call the editor. Nedim Ardoğa (talk) 11:07, 9 December 2020 (UTC)
