This Monday (Nov. 14), the moon will be the closest it’s been to Earth in nearly 69 years. Coinciding with a full moon, this lunar event has earned the title of a“Supermoon.” Astronomers expect it to appear roughly 14 percent larger and 30 percent brighter, brushing within 85 miles of its closest possible approach to Earth. This will be the moon’s closest approach to Earth since Jan. 26, 1948, which won’t occur again until November 2034. Though it’s forecasted to be noticeably brighter, the size difference may be subtle when viewed with the naked eye. Because of the close approach, tides are expected to rise some 2 inches higher on Nov. 14.
