Good news for sky watchers and selenophiles, tonight’s full moon is set to be the biggest and brightest of the year, according to NASA. The “super snow moon” as it is being called, will cross the skies this Tuesday evening, Feb. 19. Super snow moon was given this name because the full moon in February is known as the "full snow moon" among Native American tribes. This is due to the heavy snowfall that often occurs at that time of the year, according to the Old Farmer's Almanac. Meanwhile, Super Moons happen when the Moon's orbit brings it to its closest approach to Earth while the satellite is full. However, according to the almanac, it is unlikely that people would be able to differentiate between Super Moons and typical full moons. “When a full moon appears at perigee [its closest point to Earth] it is slightly brighter and larger than a regular full moon—and that's where we get a ‘ Super Moons’,” NASA said on its website, noting that the phrase was coined in 1979. See kids.... we didn't even have Super Moons when we were young.
