We performed a detailed thermophysical model analysis by using the spin and shape model recently derived from applying a two-period Fourier series method to a large sample of well-calibrated photometric observations. We found that the tumbling asteroid Apophis has an elongated shape with a mean diameter of 375(-10)(+14)m (of an equal volume sphere) and a geometric V-band albedo of 0.30(-0.06)(+0.05). We found a thermal inertia in the range 250-800 Jm(-2) s(-0.5) K-1 (best solution at Gamma = 600 Jm(-2) s(-0.5) K-1).
