Variable Star Photometry and The Transit method are extremely viable means of detecting extrasolar planets. TrES-3b was successfully detected and the magnitude change was 0.03 percent away from the estimated value. The drop in magnitude was significant enough for the data to be ruled as accurate and the planet as existent. Extrasolar planet detection is extremely important in learning more about the properties of our solar system and solar systems that are thousands to billions of light years away (Cowan, Nicholas American Geophysical Union, 2014). Extrasolar planets, such as Kepler 22b contain conditions that resemble earth and could potentially be habitable, which is a large discovery that stresses the importance of extrasolar planet detection.
