Super Blood Moon on Sunday!


The full moon Sunday will appear larger, brighter and redder than usual. As it so happens, it will also be going through a lunar eclipse. The two events—the “supermoon” and the eclipse—have occurred in tandem only five times since the turn of the 20th century. (Newsweek)

Discussion Ideas

  • What is a supermoon? Watch the short NASA video above for some help.
    • A supermoon appears up to 14% larger and 30% brighter than normal.
      • A supermoon is a result of the moon’s elliptical orbit. The moon reaches the point farthest from the Earth at its apogee, and the closest point to the Earth at its perigee. A supermoon is simply a perigee full moon—when it is almost 50,000 kilometers (31,000 miles) closer to Earth than at its apogee. A supermoon appears 14% and 30% brighter than an apogee full moon.


  • What is a “blood moon”? Watch the NASA video or take a look at our beautiful photo for some help.
    • A blood moon is simply another name for a lunar eclipse. A lunar eclipse happens when the moon passes behind the Earth and into its shadow. The shadow gives our favorite satellite a red tint, earning it the nickname “blood moon.”
