1. An aerosol generating system comprising:
a holder configured to generate aerosol by heating a cigarette;
a cradle having an inner space for accommodating the holder, wherein the holder is moveable in the inner space of the cradle;
at least one sensor configured to sense variation in a position of the holder in the inner space of the cradle; and
a controller configured to make a prediction about insertion of the cigarette into the holder based on sensing of the sensor, and start first preheating of a heater of the holder before the cigarette is inserted in the holder based on a result of the prediction, and start second preheating of the heater of the holder after the cigarette is completely inserted in the holder,
wherein the first preheating and the second preheating have different target temperature profiles.
