Astronomers use the Transit Timing Variations method to estimate the number of planets in the Milky Way. This technique involves monitoring the brightness of stars and detecting periodic dips in brightness caused by planets transiting in front of them. The more planets that are discovered, the more astronomers can extrapolate the average number of planets per star. With over 700 confirmed planets, the average of 16 planets per star leads to the conclusion that there are at least 160 billion planets in our galaxy. The KELT telescope and similar instruments enhance these discoveries by allowing astronomers to survey larger areas of the sky and detect more transits.
