Talk:809 Lundia

Estimates about the binary
What is known is H=11.8, orbital period=15.4 hours. If albedo and density of the components were known, one could calculate their size and distance from each other. To get ballpark estimates of the likely range (better than "unknown") I tried a few values: Furthermore, equal size of the components was assumed. Then the range of size, mass and orbital distance values in the infobox were then been calculated using basic formulae. Strangely to get a size of 6km for the components, a very high albedo of 0.6 is needed. This seems unlikely! Deuar 17:19, 14 May 2006 (UTC)
 * Albedo = 0.2 to 0.423 (the higher value is Vesta's albedo, relevant since these are V-type asteroids)
 * Density = 1 to 3.4 g/cm³ (lower value for a typical rubble pile, higher is Vesta's density)
