Scientific paper

In this paper we report the all exoplanets that are discovered to date by the transit method. Also, we present the limit of detection by this method using the small instruments, and the specific information that can be deducted from the transit method. In addition, we present the detection and characterization of HD 189733b, the peculiarity of this exoplanet is that the flow of the target star is decreased significantly (∼3%) during the transit. We determined the radius of the exoplanet 1.27 ± 0.03 RJ, the impact parameter 0.70 ± 0.02, and the inclination of the orbit 85.4 ± 0.1°. The transit of the extrasolar planet HD 189733b is already done using the larger telescope. In this study, we used during the observation a telescope of modest size.
