While researching a topic, a student has taken the following notes: Kepler-186f is an Earth-sized exoplanet located in the Cygnus galaxy.It has an orbital period around its home star of roughly 130 days.The planet was detected using a common method called transit photometry, which measures changes in the brightness of the system’s home star when the planet passes in front of it.Analysis of three years of data was required to confirm Kepler-186f’s existence.The student wants to make and support a generalization about detecting exoplanets using transit photometry. Which choice most effectively uses relevant information from the notes to accomplish these goals?The exoplanet Kepler-186f has an orbital period of 130 days and required three years of transit photometry data to confirm its existence.eliminateAs demonstrated in the case of Kepler-186f, it can be hard to confirm the existence of certain exoplanets. eliminateDetecting exoplanets using transit photometry can often require several years of observation, as demonstrated by the case of Kepler-186f, which required three years of data to confirm.eliminateTransit photometry measures changes in brightness as planets like Kepler-186f pass in front of their home stars.

From 2009 to 2013 the Kepler space telescope __________ 150,000 stars in an effort to discover Earth-like planets orbiting those stars. Recent advances in technology have made the search for these exoplanets, planets outside our solar system, possible.
