Tell your teacher that the perihelion of the moon was even closer than this one will be on January 19, 1992. This happens every 18 years, 11 days and eight hours on average (Saros cycle). The moon moves away from the Earth 3.8 cm (1.52 inches) per year. so this time the Moon is more than 68.4 centimeters further away, and that's not accounting for the 11 days and 8 hours.I've already commented in other answers in the previous 24 hours about the possible connection between the super-moon and the Japan earthquake. I know my reasoning will probably be disputed by some YA members, so I'm not commenting further right now.
