  • In the span of just over three years, humanity will have witnessed both the shortest total lunar eclipse of the 21st century as well as the longest. According to NASA, the shortest total lunar eclipse this century will see occurred on 4 April 2015 and lasted a mere 4 minutes and 48 seconds. The longest, spanning 1 hour 42 minutes and 57 seconds, is slated to occur on 27 July 2018. The length of a total lunar eclipse varies based how far the moon is from the Earth at the time of the eclipse. As described by EarthSky, the 27 July eclipse will occur when the moon is coincidentally at its farthest point from Earth: Unfortunately for readers residing in portions of North America that are not on the most eastern side of Newfoundland, they will effectively miss out on the action. However, the eclipse will be visible, to some degree, from every other continent on the planet. How does this century’s longest duration total lunar eclipse compare to other centuries’ record holders? Though the Gregorian calendar was not a thing at the time, the longest total lunar eclipse occurring in the five millennia (or 50 centuries) between 2000 BCE and projected into 3000 CE occurred on 31 May 318 CE and lasted 1 hour, 46 minutes, and 36 seconds — a full three minutes and 39 seconds longer than this July's eclipse will be.
