Assigned ID: 111 ----- Submission 1 (Thu Jan 20 23:10:35 GMT 2005) ----- We propose to study the problem of finding terrestrial mass planets with HST by measurement of the transit timing deviations of gas giant planets due to a perturbing terrestrial planet. We will develop the analytic theory of n:1 resonances and inclined planets, we will carry out simulations to determine the sensitivity of HST observations to terrestrial planets, we will explore the best observing strategy, and we will make available to the community routines for finding the best-fit parameters of a perturbing planet. We will apply our codes to the existing HST observations of 25 transits of HD 209458.
