Which of the following will allow you to learn something about a transiting planet's atmospheric composition? Which of the following will allow you to learn something about a transiting planet's atmospheric composition? Compare spectra obtained before and during an eclipse. Use the Doppler method to study the planet throughout a cycle from one transit to the next. Calculate the planet's size, and then use size to infer what its atmospheric composition must be. Look for slight variations in the time between transits.

Compare spectra obtained before and during an eclipse
