The heating and ablating rates of asteroidal meteoroids are calculated at their stagnation point assuming the meteoroids to be spherical in shape. The flow around a meteoroid is assumed to be inviscid and thermc-chemically in equilibrium. Radiation intensity is calculated line-by-line. The calculated heating/ablation rates decrease with nose radii, peak at altitudes between 30 and 40 km, and not always increase with flight velocity. Heating rate can be as high as 230 kW/cm~2 and ablation rate can be as high as 250 kg/(m~2-s). They can be higher or lower than the values calculated using the Rosseland approximation, and do not asymptotically approach the Rosseland values at high densities. The magnitude of the heating/ablating rates is determined mostly by the weak radiation mechanisms.
