Abstract
The number of known transiting extra-solar planets has now reached 40, enough for stastistical properties to start emerging. Due to the nature of the transit method, these planets all orbit very close to their parent stars, so close that tidal forces can be strong enough to modify their orbit. After discussing the main characteristics of the present sample of transiting planets, some suggestive indications of the importance of tidal effects on their orbital parameters will be presented.
