The observation of exoplanets orbiting ancient stars allows us to understand not only distant solar systems inhibiting these worlds but our own solar system as well. In particular, the method of locating and analyzing these exoplanets allows us to delve into a deeper understanding of host stars and planets themselves. However, there are a limited number of methods in finding these exoplanets, as well as difficulty in overcoming observing inaccuracies when perceived from Earth. With the transiting lightcurve method and the collection of data from the Transiting Exoplanet Surveying Satellite (TESS), we are able to more efficiently observe details of transiting planet events through the change in flux of a host star. This results in thousands of stellar light curves to examine in order to detect planet candidates, binary stars, variable stars, and other stellar phenomena. The successful finding of an exoplanet through this method allows a multitude of future investigations to take place such as atmospheric analysis and astrobiological implications.
