Evaluations of the Methods for Planet Searching and Detection

As a matter of fact, with the continuous progress of science and technology, it is increasingly important for people to study whether there are other planets in the universe. With this in mind, the aim of this paper is to analyze several commonly used planet search methods and summarize their advantages, disadvantages as well as scope of application. To be specific, by studying and investigating the radio velocity method, the transit method and the direct imaging method, it is found that the radial velocity method and the transit method are the most popular methods for discovering exoplanets. According to the analysis, the state-of-art observation results, current drawbacks as well as prospects are discussed. In reality, these studies are essential for obtaining the knowledge of planetary formation and planetary distribution in the Universe, and provide further impetus to human exploration of the Universe. Therefore, this study is of great scientific significance and applied value and these results shed light on guiding further exploration of planet searching.
