LD: Lunar distance (1 LD = 384,402 km or 0.00257 AU)
AU: Astronomical unit (1 AU = 149,597,870.7 km or 389.5777 LD)
Size: estimated in meters, based on albedo = 0.15 (do not rely on it)

Diameter Estimation [in kilometers]

A function of absolute magnitude (h) and visual geometric albedo (a) assuming a spherical object with a uniform surface.
Formula in PHP: $D= pow(10,(0.5*(6.259 - log10($a) - 0.4 * $h)))
