The major planets plus all known asteroids of diameter 70 km or greater were numerically integrated for 500 years in a detailed study of the short-term effects of the asteroids - viewed as a noise source - on the orbital motions of the inner planets. Preliminary results are presented. Asteroid perturbations cause the planetary semimajor axes to oscillate (with the exception of that of Mercury, which drifts) and the other orbital elements to exhibit secular drifts. Short-period perturbations in semimajor axis range in amplitude from less than 0.5 m for Mercury to 200-300 m for Mars. Power spectra exhibit a forest of individual spectral lines with an underlying noise floor. Real power exists at all frequencies, roughly 2-4 orders of magnitude below the spectral peaks. The effects of a single massive asteroid are qualitatively the same, but with fewer individual spectral lines. Quantitatively, the noise floor drops by an order of magnitude and appears to scale linearly with the total asteroid mass. The shape of the noise distribution is discussed.
