  In this research, 14 light curves of 10 hot Jupiter exoplanets available on
Exoplanet Transit Database (ETD) were analyzed. We extracted the transit
parameters using EXOFAST software. Finally, we compared the planet's radius
parameter calculated by the EXOFAST with the value at the NASA Exoplanet
Archive (NEA) using the confidence interval method. According to the results
obtained from this comparison, there is an acceptable match for the planet's
radius with NEA values. Also, based on the average value of 350 mm optics in
this study, it shows that the results obtained using small telescopes can be
very significant if there is appropriate observational skill to study more
discovered planets.
