supermoon

There has been a lot of popular media coverage of the “supermoons” the past few years.  That is not a scientific term, but one coined about thirty years ago. It is more on the side of astrologers than astronomers.

People know that the Moon affects tides. Many people suspect that it affects people and animals, although much of that falls into my “moon lore” category.

But it is great that media coverage pf the term has people looking up at the night sky.  Tonight’s Full Moon will appear about 14% larger than usual at a point in its journey across our sky.

A “supermoon” can be a New Moon or a Full Moon when it occurs at roughly the same time the moon is nearest Earth in its monthly orbit. That is properly called perigee, the term for the moon being at its closest point to Earth.
