String theory imposes modifications to Einstein's equations of classicalgeneral relativity. Consequently, we calculate the additional corrections tothe classical tests: the perihelion precession of Mercury, the deflection oflight rays by the sun, and the gravitational redshift which should be presentif these modified equations hold. In each case, we determine --- quiteconsistently with expectations --- that the stringy effects are much too smallto be measured.
