Greek word meaning repetition: tables 2. 1 and 2. 2 in your textbook list the solar and lunar eclipses up to 2022. review these to see when the next such event occurs. An interesting fact (coincidence?: solar eclipses happen because of an interesting coincidence. Moon"s diameter is 400 times smaller than the sun"s. 400 times further from the earth than is the moon (on average).
