What happens supermoon?

Moon phases are determined by the relative positions of the Moon, Earth, and Sun. We see the Moon go through a changing cycle of phases each month due to its orbital motion around Earth and the changing geometry with which we view it.
How does the super moon affect us?
Simply put, an extra-close new or full moon causes higher-than-usual perigean tides. What's more, given the change in distance between the moon's farthest and closest points, the full moon can appear as much as 14% larger in the sky and 30% brighter to our eyes than at minimum size and brightness.
Who named supermoon?
astrologer Richard Nolle The term supermoon was coined by American astrologer Richard Nolle in 1979 to describe both a new and a full moon occurring at or near (within 10 percent of) perigee. However, supermoon came to denote the more-restrictive meaning of a full moon at perigee.
How does the moon affect people?
The lunar cycle has an impact on human reproduction, in particular fertility, menstruation, and birth rate. … In addition, other events associated with human behavior, such as traffic accidents, crimes, and suicides, appeared to be influenced by the lunar cycle.
How does the moon turn red?
The moon is fully in Earth's shadow. At the same time, a little bit of light from Earth's sunrises and sunsets (on the disk of the planet) falls on the surface of the moon. Because the light waves are stretched out, they look red. When this red light strikes the moon's surface, it also appears red.
