I wonder if someone who knows more about this than myself could update this article. Apparently there is an estimate (Mainzer, A. et al. (2013) Astrophys. J.) of the albedo that significantly increases the diameter to 0.472 km. This would imply that the Palermo is also significantly under estimated. I believe this would make it positive if the calculation were redone in light of the additional information. — Preceding unsigned comment added by 188.8.131.52 (talk) 17:49, 12 March 2014 (UTC)
Do you have a link to Amy's paper? I would love to read about the measurement uncertainties. -- Kheider (talk) 01:04, 22 March 2014 (UTC)
 - It give a diameter of 0.472 +- 0.045 km much less than the uncertainty based on M alone. — Preceding unsigned comment added by 184.108.40.206 (talk) 16:19, 4 April 2014 (UTC)
