A Buck “supermoon” will grace the skies overnight Wednesday – the biggest one of the year – as our neighbour arrives arrives at its closest point to the Earth.
NASA says that when a full moon appears at the so-called perigee, in this case a distance of 357,264 kilometres away, it is larger than a regular full moon.
“The supermoon can be up to 14 percent larger and 30 percent brighter than a full moon at its apogee (its farthest point),” NASA says.
Because the lunar orbit is not a perfect circle, but a slightly elongated ellipse, its distance from Earth changes.
