We report on the measurement of transit times for the HD 209458 planetary system from photometry obtained with the MOST space telescope. Deviations from a constant orbital period can indicate the presence of additional planets in the system that have not yet been detected, potentially with masses approaching Earth mass. The MOST data sets of HD 209458 from 2004 and 2005 represent unprecedented time coverage with observations spanning 14 and 44 days and monitoring 2 and 13 transits, respectively. Transit times for the eclipses are being analyzed and implications for the planetary system will be discussed.
