Abstract : On the basis of reported optical measurements of iron and stony meteorites, upper and lower limits for solar absorptance and hemispherical emittance of such surfaces have been tentatively established. Temperatures of three classes of meteoroids, none larger than 10 meters in radius have been calculated for various orbits and alpha/epsilon ratios. These classes are light chondrites, dark chondrites, and the irons. Temperatures for a meteoroid in a Mercury orbit range from 100C for a light chondrite to 400C for an iron. (Author)
