Estimates of the maximum diurnal Yarkovsky drift for asteroid 7343, which assumes zero obliquity. Maximum drift (solid line) is calculated for minimum diameter, maximum albedo, minimum density. Nominal drift (dashed line) is calculated for nominal diameter, albedo and density. Minimum drift (dotted line) is calculated for maximum diameter, minimum albedo, and maximum density measured for asteroids. The Vokrouhlický et al. (2000) model is plotted as the darker line while the drift rate from Farinella et al. (1998) is plotted using the lighter line.
