Given that Planet_1 has a shorter orbital period and is hosted by a more massive star, it is determined that Planet_1 has a 1.65 times higher probability of transiting compared to Planet_2. The goal is to maximize the chances of observing a transit, leading to the conclusion that Planet_1 is the preferred candidate for observation."}
